频率选择表面结构吸波体的电磁特性研究
Study on the electromagnetic properties of frequency selective surface absorber
摘要
Abstract
The reflection characteristics, transmission characteristics and the phase relationship between the incident and reflection waves were simulated for the FSS units with butterfly structure and square-ring structure using FDTD, and the simulation results were analyzed and discussed. The results show that the destructive interference of electromagnetic waves is a main reason for the wave absorption of FSS absorbers. When the phase difference between incident and reflection waves is 2nπ, the wave absorption performance of FSS absorbers reaches the best. The center frequency of FSS absorbers decreases with increasing thickness of dielectric material, and the center frequency of the FSS absorber with butterfly structure is 6.4 GHz when the thickness of dielectric material is 5mm. The non-normal incidence deteriorates the transmission characteristics of FSS absorbers. With the increase of incident angle, the high-frequency part of the transmission characteristics of FSS absorbers shifts to low frequency.关键词
