In this paper, the finite element method is used to calculate the extinction optical properties and electric field distribution of gold core silver shell nanorod-gold film nanostructures. The volume ratio of silver and the length diameter ratio of core-shell nanorods can be changed by controlling the thickness of silver layer, which can realize the regulation of the longitudinal mode peak position from 600 to 900 nm. The electric field intensity of the core-shell nanorod-gold film structure increases with the increase of the volume ratio of silver. Silver is the plasmon material with the smallest loss in the visible light region, due to its small imaginary part of the dielectric function and lower plasma damping than gold. Therefore, with the increase of the volume ratio of silver, the extinction spectrum intensity of the gold core silver shell nanorod-gold film increases obviously, and the blue shift of the peak position and the narrowing of the full width at half maximum of the wave shape are obvious changes. At the same time, the structure gap confines the light to the deep sub wavelength range, which will produce a hot spot in the gap, which will enhance the electric field.

A new singularity cancellation transformation is presented for calculating weakly near-singular integrals in time-domain integral equations. On one hand, the singularity cancellation method is a numerical technique for singularity treatments, which is relatively simple and kernel-independent. The integral kernels of time-domain integral equations depend on the temporal basis functions and solution methodologies, which benefit from the generality of cancellation transformations. On the other hand, the singularity cancellation transformations for weakly near-singular integrals are inefficient on the deformed triangular domain, which is referred to as shape-dependence in this paper. The shape-dependence issue is a main problem of singularity cancellation methods. Therefore, the reason of shape-dependence is investigated via the theoretical analysis in this work. Second, a new singularity cancellation transformation is proposed for calculating weakly near-singular integrals in time-domain integral equations, which have fast and consistent convergence rate for both regular and irregular triangles. Some numerical results are given to show the effectiveness of the proposed variable transformation.

This paper presents the shielding effectiveness (SE) of the ground vias in conformal-shielded System-in-Package (SiP) by analyzing three main radiation leak paths separately. The SE of the ground vias can be submerged by radiation from those three paths and the overall SE of SiP is determined by the weakest-shielded path. The method proposed and the findings in the work will assist to decrease the redundant design of ground vias in SiP.

A new type of ultra-wideband cylindrical conformal array antenna is presented. Considering that the microstrip antenna has the advantages of small size and easy conformity with the surface of the carrier and the non-frequency-dependent characteristics of the log periodic antenna, the microstrip log periodic antenna is selected as the unit of the array antenna. Then the fractal Koch curve structure is adopted to improve the traditional antenna. Then an array of five log periodic Koch antennas conformal with a hollow cylindrical carrier is designed. Simulation results show that when five log periodic antenna elements work simultaneously, the frequency range of S11< -10dB is 3.57GHz-12.95GHz. Its operating bandwidth is 9.38 GHz and relative bandwidth is up to 114%, meeting the requirements of the working bandwidth of UWB antenna. Through the reasonable space layout and parameter optimization, the design has achieved miniaturization, , ultra-wide band, high gain, simple structure and so on. It is suitable for communication, reconnaissance and electronic countermeasures.

In order to build the characteristic database of typical radar target, it is necessary to solve the problem that the large amount of radar data is difficult to be stored and processed directly. It is an effective way of data compression to represent the original data with a small amount of scattering centers. Based on the idea of one-dimensional GTD model, the scattering center is extracted for data compression and storage. At the same time, considering the small segment missing phenomenon of radar detection in real scene, a prediction method of RCS (radar cross section) sequence based on neural network is proposed. Taking the global-hawk as an example, the results show that under the premise of controllable error, the method of extracting scattering center has a high compression ratio. Compared with the simulation results of FEKO software, the prediction sequence of neural network has a higher degree of fitting with the simulation results, which shows that the prediction of RCS missing segment by neural network is completely feasible.

In this paper, the stochastic integral equation method (SIEM) is proposed to calculate the electromagnetic scattering from the one-dimensional Gaussian rough surface. In the SIEM, the statistical parameters of the Gaussian rough surface are firstly included in the Green’s function. And the new Green’s function is used to get the new integral equation. Then the method of moments is applied to solve the new integral equation. The accuracy of the SIEM is shown by comparing with the statistical average of multiple samples through the Monte Carlo method. And, the sample of the Gaussian rough surface is not needed to simulate in the SIEM.

As a bridge linking propagating waves and surface waves, reflective metasurfaces play a significant role to manipulate electromagnetic (EM) waves. Without transmission coefficients, however, the effective constitutive parameters (εeff, μeff, neff, zeff) of reflective metasurfaces cannot be retrieved by conventional theory. In this work, an innovative method using single S-parameters (only S11) is proposed to retrieve the effective EM parameters for reflective metasurfaces. The validity of the method is demonstrated by imping TE-polarized EM waves normally and obliquely on the single- and multiple-layer unit cells. The retrieved results match well with each other corresponding to the assumption of passive homogeneous mediums. This method is beneficial for the design of reflective metasurfaces and other applications of anomalous reflection.

In this paper, a novel three-dimensional (3-D) Frequency Selective Surface (FSS) which is independent of incident angle is proposed. By mapping circular aperture unit elements of two-dimensional (2-D) FSS to spheres, an innovative 3-D FSS which contains annular aperture unit elements is designed. Through controlling structure parameters, the resonant frequency shift characteristics of the proposed 3-D FSS under oblique incidence can exhibit opposite tendency, which provides a possible way to offset the resonant frequency shift of the dielectric slab caused by different incidence angles. The performance of the proposed 3-D FSS loaded with dielectric slab demonstrates excellent resonance stability over a large range of oblique incidence, and the resonance frequency remains constant for different incident angles, even valid up until 80 degree.

Gesture is an important way of communication in people’s daily life, helping people to understand each other in some special cases. Most of recent research is of the optical field, which is limited when in dark or with obstacles, while the microwave can address these issues with its all-day, all-weather, and penetrability properties. Programmable metasurfaces have been widely applied in many fields since it’s programmable, flexible, controllable and multifunctional. In this paper, we realize the gesture detection and recognition using deep learning neural network, Faster Region-based Conventional Neural Network (Faster R-CNN) and Conventional Neural Network (CNN). The detection and recognition here are based on the microwave images with programmable metasurface. The accuracy of gesture detection and recognition are both very high, beyond 90%.
