摘要
研究了一种由多层介质交替排列的1维微波光子晶体,应用传输矩阵法计算和分析了该结构周期数、波的入射角、介质的相对介电常数以及介质层厚度等对其频率选择特性的影响,并具体给出了一个可行的设计方案。所设计的频率选择表面在3.2-4.0 GHz频率范围内,反射系数大于0.99,在9.5-9.7 GHz频率范围内透射系数大于0.98。
The one-dimensional microwave photonic crystal（MPC） composed of alternating multilayer media is studied.Transmission matrix technique is used to theoretically analyze the influence of period number,wave incidence angle,medium＇s relative dielectric constant and dielectric sheet thickness on its frequency selection characteristics.Finally,a feasible MPC frequency selective surface is designed,whose energy reflectance in 3.2～4.0 GHz and transmittance in 9.5～9.7 GHz are greater than 0.99 and 0.98,respectively.
