Design Method for Practical EM Absorbers and Oblique Incidence Measurement Setup at Microwave to Millimeter Waves

首先，提出了斜入射波作用下吸波板的设计方法。在斜入射条件下，吸波板的TM波和TE波反射特性表现出各向异性。通过使用本研究提出的线阵列片，可以在几乎相同的频率范围内匹配斜入射的反射系数。其次，开发了使用角反射器的斜入射测量装置。在这项研究中，电磁吸收器在毫米波斜入射下的吸收特性进行了评估。

First, the method of designing EM absorber panels under oblique incident waves is proposed. TM and TE wave reflection characteristics of the absorber panel show its anisotropy under oblique incidence. By using the wire array sheet proposed this study, reflection coefficients in oblique incidence can be matched at almost the same frequency range. Next, the oblique incidence measurement setup using a corner reflector is developed. In this study, absorption characteristics of EM absorbers at millimeter waves under the oblique incidence are evaluated.
