Particle Swarm Optimization (PSO) has been successfully applied in the design and optimization of electromagnetic structures. Combined with FDTD technique, PSO is applied in the design of frequency selective surfaces. Together with the GPU acceleration, the FDTD program runs about 100 times faster while preserves the broad-band nature of the algorithm. Standard PSO and binary PSO are applied to deal...
Frequency Selective Surface (FSS) is popularly applied as an electromagnetic filter. Frequency response of a perfect FSS should remain unchanged even if the angle of incidence and polarization vary dramatically. Sometimes, the transmission curve of specific FSS is designed to decrease quickly when it is not in band-pass range. It is difficult for single FSS to achieve the goal. Fortunately, multilayer...
In this paper frequency selective surface (FSS) is analyzed by a method. It is the mixture of the mutual impedance approach and the spectral approach. To evaluate the transmission coefficient educed from this method, we need to apply the numerical algorithm. This paper adopts the method of moments to evaluate it. Compared with other ways, this technique spends less computing time and calculates more...
