摘要

本文给出了近似求解二维周斯渐变形状吸收体构成的微波辐射计外部定标负载辐射特性的方法．计算结果与数值方法、实验测量进行了比较．当结构周斯小于0．75倍波长，即D＜0．75λo时近似算法有良好的精度．

Abstract

This paper presents an asymptotic procedure hased on transmission line analogy to determine the radiative characteristic of external loads loads composed of doubly periodic tapered microwave ab sorbers.The results are compared with numerical and experimental dats.When the period of the tapered absorber is less than 0.75 wavelength

the approsimate calculation is fairly well.
