Focuser concentrates the energy in a region through the lens, which can enhance the interaction between the field and the matter. It has important application value in engineering. With the tapered structure of the spoof SPPs transmission line, the electromagnetic wave in the gap between adjacent structures is transformed into a planar waveguide mode. These electromagnetic waves are confined in the gradually decreasing gap, resulting in a large amount of energy accumulation at the tip of the taper to form a field focusing effect. In this paper, a type of spoof SPPs focuser is designed, a focusing method of SPP wave is established through a conical transmission line on the surface at microwave band, and the application range of its focusing effect is explored.

ABSTRACT The continuous emission of greenhouse gases leads to the sharp rise of environmental temperature. Its content and distribution also affect the atmosphere radiation, climate characteristics, stratosphere troposphere exchange (STE) and circulation in the near-tropopause region. Methane is the second most important greenhouse gas after carbon dioxide, and its concentration has strong gradients near the tropopause. Therefore, the sensitivity, accuracy of methane detection approach in extreme environment have been greatly restricted, and this has become a technical bottleneck for low-temperature and low-pressure gas detection. To address this, a novel 3-dimensional compensation model of temperature and pressure is reported based on the simulation of methane absorption characteristic. Through a detailed investigation, the simulation system and compensation model are evaluated, the detection accuracy is improved by an order of magnitude; the minimum detection limit is ~0.012ppm with integration time is 59s.

Large-scale integrated optical phased arrays (OPAs) can provide small angular resolutions for LiDAR applications. However, strong coupling between waveguides will occur under sub-wavelength element pitch, posing a limitation to the development of high-performance OPAs. To reduce the coupling between waveguides, high-reflection boundaries made up of high-contrast gratings (HCGs) are arranged on both sides along silicon strip waveguides. At the same time, light is radiated into free space with controlled radiating rates by the HCGs periodically perturbing evanescent fields of silicon strip waveguide. Simulation results show that the crosstalk reduction of the designed array is over 10 dB compared to traditional waveguide array with identical sizes within the wavelength ranges of 1500 ~ 1590 nm. Furthermore, a weak radiation strength of 1.15 mm-1 is achieved, yielded an effective radiation length up to 2 mm. Therefore, combining with the low crosstalk between under the deigned sub-wavelength element pitch of 0.645λ and the long effective radiation length, our design holds promise for high-performance OPAs with a large field of view and a high angular resolution.

We have studied the coupling effect of topological photonic states in a double-channel magneto-optical photonic crystal waveguide by introducing a two-layer ordinary alumina (Al2O3) photonic crystal as the coupling layer. Interestingly, for the structure with the same widths of the two channels, the electromagnetic wave propagates one-way to the right side and exhibits wave-like path within the waveguide due to the coupling effect of topological photonic states. This unique property provides an effective way to achieve desired power ratio between two right outputs by terminating the structure at different length of waveguide. Moreover, the power ratio can be tuned by the external magnetic field conveniently. As for an asymmetric waveguide with different channel widths, there exist two asymmetric one-way topological photonic states (i.e., the odd-like and even-like modes) in the bandgap. The eigenfield analyses show that the electric field of odd-like mode is stronger in the lower channel, while that of even-like mode is contrary. As the old-like mode propagates rightwards, electromagnetic waves in the two channels couple with each other via the coupling layer, then the power in the upper channel gradually transfers to the lower channel, and finally reach almost 100% transmittance in the lower output. However, the case for the even-like mode is totally contrary. These results hold great promise for many application fields such as signal transmission, optical modulation, and the design of topological devices.

Jet polishing plays an important role in ultra-precision machining. In this paper, the effects of slotted and slotless nozzles on micro jet machining are investigated. The pressure distribution and magnitude of the two nozzles on the workpiece were first calculated by finite element simulation software. Then a set of comparative tests were conducted on two single crystals of silicon. The results showed that the pressure distribution of the slotless nozzle was more uniform compared to the slotted nozzle, and the pressure value of the slotless nozzle on the surface of the workpiece was greater. In addition, the slotless nozzle is more capable of improving the surface roughness of the workpiece in the same time.

Recently, most of the record-breaking PSCs are used formamidinium lead triiodide (FAPbI3) as the perovskite absorber due to its narrow bandgap. To stabilize the α-phase of FAPbI3, one of the common ways is introducing MAPbBr3 (where MA is methylammonium) into the perovskite layer. However, the MA+ will sacrifice the thermal stability of devices, while the incorporation of Br– will enlarge the optical bandgap and eventually decreased the photocurrent of PSCs. Here, a convenient strategy is presented to sequentially deposit stable FAPbI3 perovskite layer without MA+/ Br– by introducing the two-dimensional (2D) perovskite materials PMACl. It is speculated that the PMACl can form a 2D structure in grain boundaries which plays the role of template for the growth of α-FAPbI3. In addition to tune the phase transition, the PMACl can improve the crystallization and smooth the morphology of perovskite. As a result, the PSCs with PMACl achieve a PCE of 16.19%, while the control device only exhibits a PCE of 10.67%. This novel method avoids introducing the MA+/ Br–, and provides a facile approach for the efficient FAPbI3 perovskite solar cells.

With the increasing requirement of lithographic resolution, the degradation of 3D mask effect on imaging cannot be ignored. The researches of its polarization properties and effect on imaging are of great significance to the development of imaging-based aberration measurement techniques and computational lithography. In this paper, a novel method for comprehensive and quantitative characterization of 3D mask effect is proposed. By comparing the far-field spectrum of Kirchhoff model and 3D mask model, the 3D mask effect is comprehensively and quantitatively characterized as the form of polarization aberration. Pupil-spectrum comprehensive analysis method and background glitch noise culling method are proposed to improve the systematicness and accuracy of 3D mask characterization. The simulation comprehensively analyzes the effect of mask line width and absorber thickness on all polarization properties of the 3D mask effect, showing that this method can provide a more comprehensive analysis of the 3D mask effect compared with the previous methods.

This paper proposed a novel pressure sensors based on polymer film with surface microstructures. Polymer film with surface microstructures have displayed unique optoelectronic and electrical properties due to the triboelectric effect. The micro-deformation and moving of polymer microstructures can product electrostatic charge. The pressure sensors can convert external pressure or mechanical deformation into electrical signal. The pressure sensor consists of one polymer film with surface microstructures and one conductive electrode layer. The regular microstructures increase the film roughness and contact triboelectric area to enhance the electrostatic effect. To enhance the performance of the pressure sensor, high-precision microstructures on soft polymer sensitive layers are fabricated using UV nanoimprint lithography to generate more triboelectric charges. The pressure sensor is prepared, which consists of grating with 3 μm- period on the surface of the elastic layer and an indium tin oxide electrode thin film. By converting the friction mechanical energy into electrical power, a maximum power of 423.8 mW/m2 and the sensitivity of 0.7 V/kPa at a frequency of 5 Hz are obtained, which proves the excellent sensing performance of the sensor.
