We theoretically investigated the plasmonic properties of aluminum-aluminum antimonide (Al-AlSb) core–shell nanorods, elucidating the influence of shell thickness and core geometry on their optical cross-sections and near-field enhancement. Through systematic computational analysis, we demonstrate that the plasmonic response is governed by the hybridization between the Al core plasmon and dielectric AlSb shell. This interaction yields a highly tunable, low-energy, bonding dipolar mode, whose localized surface plasmon resonance (LSPR) exhibits a pronounced and systematic redshift from the visible to the near-infrared (NIR) region with increasing shell thickness. Meanwhile, a high-energy, anti-bonding mode emerges in the ultraviolet (UV) spectrum, manifesting as a distinct spectral peak or shoulder with quadrupolar characteristics. The interplay between core dimensions and shell thickness provides a robust mechanism for tailoring these hybridized modes, enabling, for larger-diameter (

D = 50 nm

) rods, a dramatic, shell-induced enhancement of absorption that switches the system from a scattering- to an absorption-dominated regime. Moreover, the nanorods exhibited intense electric field enhancement at their tips, which was spectrally tuned by the shell thickness without significant quenching. These findings establish the Al-AlSb nanorods as a versatile platform for applications in surface-enhanced spectroscopy, photocatalysis, and advanced optoelectronic devices.

从理论上研究了铝-锑化铝（Al-AlSb）核-壳纳米棒的等离子体特性，阐明了壳厚度和核几何形状对其光学截面和近场增强的影响。通过系统的计算分析，我们证明了等离子体响应是由Al核等离子体与介电AlSb壳层之间的杂化控制的。这种相互作用产生了一种高度可调的、低能的键合偶极模式，其局部表面等离子体共振（LSPR）随着壳层厚度的增加，呈现出明显的、系统的从可见光到近红外（NIR）区域的红移。同时，在紫外光谱中出现了高能量的反键模式，表现为具有四极特征的明显的光谱峰或肩。芯尺寸和壳层厚度之间的相互作用为调整这些杂化模式提供了强大的机制，对于直径更大（D=50nm）的棒，壳层诱导的吸收显著增强，将系统从散射主导转变为吸收主导。此外，纳米棒在其尖端处表现出强烈的电场增强，这种增强受壳厚度的光谱调节，而没有明显的淬火。这些发现奠定了Al-AlSb纳米棒作为表面增强光谱、光催化和先进光电器件应用的通用平台。

This study presents a novel Ti-Si3N4 bilayer hole-array metamaterial absorber, surpassing traditional metal-insulator-metal (MIM) three-layer designs. Leveraging titanium’s optical losses and silicon nitride’s dielectric properties, it achieves 97.11 % average absorptance across 200–3000 nm, with polarization and angle insensitivity. Its simple bilayer structure enhances fabrication feasibility, while maintaining ∼90 % photothermal conversion efficiency at 1000 K (CF = 1000). Simulations reveal synergistic localized surface plasmon resonance, magnetic resonance, cavity modes, and inductor-capacitor effects driving ultra-broadband absorption. Outperforming existing designs in bandwidth and simplicity, this absorber is ideal for solar energy harvesting, photothermal conversion, and electromagnetic stealth.

本研究提出了一种新型的Ti-Si3N4双层孔阵列超材料吸收体，超越了传统的金属-绝缘体-金属（MIM）三层设计。利用钛的光学损耗和氮化硅的介电特性，在200-3000 nm范围内达到97.11 %的平均吸光度，具有极化和角度不敏感。其简单的双层结构提高了制造的可行性，同时在1000 K （CF = 1000）下保持~ 90 %光热转换效率。模拟揭示了协同局域表面等离子体共振、磁共振、腔模式和电感-电容效应驱动超宽带吸收。这种吸收器在带宽和简单性方面优于现有设计，是太阳能收集、光热转换和电磁隐身的理想选择。

The thickness of the C₆₀ electron-transport layer (ETL) is a crucial parameter in inverted MAPbI₃-based perovskite solar cells (p-i-n PSCs). However, the optimal thickness reported in the literature spans a wide range, often because of differences in device architecture, deposition method, and underlying layer morphology. Here, we present a systematic study of thermally evaporated C₆₀ films of 15, 25, and 50 nm thicknesses, examining their impact on film morphology, charge-carrier dynamics, and PSC devices performance. Among the examined thicknesses, for the inverted MAPbI₃-based PSCs a 25 nm C₆₀ layer achieves the optimal balance between resistance and current leakage. It maintains low surface roughness, accelerates charge extraction (126 ns), prolongs carrier recombination lifetime (664 ns), minimizes series resistance and maximizes shunt resistance, resulting in the highest average power conversion efficiency (PCE) (13.51 ± 1.18 %) and champion PCE (15.19 %) under AM 1.5 G. We identify three competing mechanisms that set the optimal C₆₀ thickness among the values we measured: incomplete surface coverage of the underlaying layer resulting in shunt resistance, increase of series resistance with the increase of the C₆₀ thickness, and emerging of new shunt pathways due to defects formation in overly thick C₆₀. The experimental results, obtained by AFM, transient spectroscopy and J–V characterization, highlight the critical role of ETL thickness in p–i–n devices and identify 25 nm C₆₀ as the best-performing thickness within the examined range, thereby defining the region to focus future optimization efforts.

C60电子传输层（ETL）的厚度是倒置MAPbI₃基钙钛矿太阳能电池（p-i-n PSCs）的一个关键参数。然而，文献中报道的最佳厚度范围很广，通常是因为器件结构、沉积方法和下垫层形态的差异。在这里，我们系统地研究了15、25和50 nm厚度的热蒸发C60薄膜，研究了它们对薄膜形态、载流子动力学和PSC器件性能的影响。在测试的厚度中，对于倒置的MAPbI₃基PSCs， 25 nm的C60层在电阻和漏电流之间达到了最佳平衡。它保持低表面粗糙度，加速电荷提取（126 ns），延长载流子重组寿命（664 ns），最小化串联电阻和最大化分流电阻，从而获得最高的平均功率转换效率（PCE）（13.51±1.18 %）和冠军PCE（15.19 %）在AM 1.5 G下。我们在测量值中确定了三种竞争机制来设置最佳的C₆₀厚度：下垫层的表面覆盖不完全导致分流电阻，随着C60厚度的增加串联电阻增加，以及由于过厚的C60形成缺陷而出现新的分流路径。通过AFM，瞬态光谱和J-V表征获得的实验结果突出了ETL厚度在p-i-n器件中的关键作用，并确定25 nm C₆₀是在所检测范围内性能最佳的厚度，从而确定了未来优化工作的重点区域。

The use of wideband and ultra-wideband antennas is pivotal for modern wireless communication systems, including 5 G and 6 G. A critical aspect of their functionality is the precise control over the operational bandwidth to ensure signal integrity and mitigate interference. In this work, we introduce a novel method for dynamic antenna control using Mie-resonant dielectric particles. We demonstrate that integrating compact, all-dielectric spherical and cylindrical resonators with a bow-tie antenna enables the creation of well-defined stopbands within its operational spectrum, effectively filtering undesirable frequencies without the losses associated with metallic elements. Furthermore, we unveil a groundbreaking thermal tuning mechanism by exploiting the temperature-dependent permittivity of ceramic materials. This approach allows for the active shifting of these stopbands, dynamically reconfiguring the antenna's operational bandwidth. Our results, validated through numerical simulations at 5 G high-band frequencies, show a new paradigm of a simple and efficient approach of antenna radiation control, paving the way for intelligent, adaptive and environmentally robust communication devices.

We consider spheroidal dielectric microparticles subject to radiation forces and torques induced by two linearly polarized weakly-focused counter-propagating Gaussian beams. Since the symmetry is lifted by the spheroidal shape of the particles the effects of both net radiation force and torque are taken into account. It is found that in the case of oblate spheroids there is a specific ratio of the semi-axes leading to anomalous drift of particles both in the lateral and the longitudinal direction. Such an effect results in displacement from the initial condition by distance up to

70 μ m

我们考虑了受两束线偏振弱聚焦反传播高斯光束引起的辐射力和力矩影响的球形介电微粒。由于粒子的球体形状提高了对称性，因此考虑了净辐射力和扭矩的影响。研究发现，在扁圆球的情况下，有一定比例的半轴导致粒子在横向和纵向上的异常漂移。这种效应导致与初始条件的位移达到70μm。

As a part of this investigation, we aim to develop a 1 × 2 multimode interferometer (MMI) beam splitter based on chalcogenide waveguides for dual RI profile simultaneous detection applications. The operating principle involves multiplexing transverse magnetic (TM) polarized light into two distinct channels, enabling the simultaneous detection of two RI profiles, which are considered as methane (CH₄) and nitrous oxide (N₂O) in this work. This approach is cost-effective, as the design integrates broadband near-infrared on-chip light emission with dispersive spectroscopic components, making it suitable for dual RI profile simultaneous detection. In this work, we focus on optimizing the width and length of the multimode interference region in the 1 × 2 MI, intending to enhance the imbalance between output ports and improve the contrast ratio. Additionally, the curvature of the S-bend waveguide is optimized to maximize output power while minimizing insertion loss. The spectral transmission characteristics of the MMI diplexer are analyzed with respect to variations in the refractive index (RI) of the sensing layer.

Self-assembly is an effective instrument for organization of nano- and microparticles to specially designed surface patterns. To obtain the uniform distribution of nano-and microparticles in mask-free self-assembly, the “coffee ring” effect should be carefully avoided. In this study, we propose an approach for effective limitation of such an effect on fused silica surfaces through femtosecond generation of laser-induced periodical surface structures (LIPSS). First, we determine optimal irradiation parameters to provide a higher ratio between LIPSS covered (treated) and untreated surface. Then we study a LIPPS formation in a scanning mode to cover the substrate by LIPSS reducing a contact angle. We demonstrate that scanning laser parameters with frequency of 1 kHz, pulse duration of 270 fs, laser peak fluence of 6.5 J/cm² and scanning period of 9 µm ensure a high rate of surface wettability adjustment (0.23 mm²/min) with a contact angle of ∼ 9 ± 0.5°. Droplet tests with colloidal solution of polystyrene sub-micron (～900 nm) particles demonstrate that “coffee ring” effect is considerably reduced with more than 50 % particles captured inside laser-scanned lines. The demonstrated results are prospective for creation of various photonic structures and systems through mask-free self-assembly.

自组装是将纳米和微粒组织成特定表面图案的有效手段。为了在无掩膜自组装中获得纳米和微粒的均匀分布，应小心避免“咖啡环”效应。在本研究中，我们提出了一种通过飞二代激光诱导周期表面结构（LIPSS）有效限制熔融二氧化硅表面这种影响的方法。首先，我们确定最佳辐照参数，以提供更高的LIPSS覆盖（处理）和未处理表面之间的比率。然后，我们研究了在扫描模式下，通过LIPSS减小接触角来覆盖衬底的LIPPS形成。我们证明，扫描激光参数为1 kHz，脉冲持续时间为270 fs，激光峰值通量为6.5 J/cm2，扫描周期为9 µm，确保了高表面润湿性调节速率（0.23 mm2/min），接触角为~ 9 ± 0.5°。用聚苯乙烯亚微米（~900 nm）颗粒的胶体溶液进行的液滴试验表明，“咖啡环”效应显著降低，激光扫描线内捕获的颗粒超过50% %。所证明的结果为通过无掩模自组装创建各种光子结构和系统提供了前景。

This research presents a novel design framework for photonic crystal fiber surface plasmon resonance (PCF-SPR) sensors, incorporating finite element simulation, machine learning (ML), and multi-objective optimization methodologies. A dataset is produced via numerical simulations, altering essential structural parameters such as big and small hole dimensions, hole spacing, and gold film thickness. A multilayer perceptron (MLP) neural network is created as a surrogate model to swiftly and precisely forecast sensor performance parameters, such as wavelength sensitivity and figure of merit (FOM). The non-dominated sorting genetic algorithm (NSGA-II) is utilized to attain the Pareto optimal frontier, with sensitivity and FOM as dual optimization objectives. The ideal compromise option is subsequently identified with the Technique for Order of Preference by Similarity to Ideal Option (TOPSIS) approach. The optimized PCF-SPR sensor attained a peak sensitivity of 21,172.80 nm/RIU and a FOM of 100.86

In this work, we present a versatile approach for designing new antennas with predetermined radiation patterns through the indirect solution of the electrodynamics inverse problem. The algorithm is based on the spherical multipolar decomposition of a given radiation pattern and its correlation and decomposition by the basis of other simpler antennas. The proposed technique enables flexible adjustment of the desired far-field distribution, without directly focusing on any other parameters other than the polarization requirements of the communication channel and the spatial distribution of the objects involved in the task. In addition to detailing the algorithm for reconstructing the antenna geometry from its radiation pattern, we provide several examples of using this algorithm. The emitter topologies obtained using this method can be applied both in novel 5G Advanced and 6G communication systems, as well as integrated into existing wireless communication and power transfer lines.

在这项工作中，我们提出了一种通用的方法，通过间接解决电动力学逆问题来设计具有预定辐射方向图的新天线。该算法基于给定辐射方向图的球面多极分解及其在其他更简单天线的基础上的相关和分解。所提出的技术能够灵活地调整所需的远场分布，而不直接关注通信信道的极化要求和任务中涉及的物体的空间分布以外的任何其他参数。除了详细介绍从其辐射方向图重建天线几何形状的算法外，我们还提供了使用该算法的几个示例。利用该方法获得的发射极拓扑既可以应用于新型5G Advanced和6G通信系统，也可以集成到现有的无线通信和电力传输线路中。
