摘要

从理论上预测了一种基于介电频率选择表面(DFSS)的高效窄带斜平面波滤波器。基于TM偏振的Brewster现象，设计了一种在10.5 GHz频率下全反射的DFSS，该DFSS采用单介质光栅，在谐振峰附近呈现极低反射率的边带。研究了所设计滤波器的角响应和光谱响应。此外，在这种结构中还考虑了介电欧姆损耗。

Design of a narrow-band filter based on the Brewster phenomenon for microwave applications

A high-efficiency narrow-band filter based on a Dielectric Frequency-Selective Surface (DFSS) has been predicted theoretically for oblique plane-wave incidence. A DFSS showing total reflection at a frequency of 10.5 GHz, based on the Brewster phenomenon for TM polarization, has been designed with a single dielectric grating, showing extremely low-reflectance sidebands adjacent to the resonance peak. The angular and spectral response of the designed filter has been studied. In addition, dielectric ohmic losses have been accounted for in this structure.
