| 摘 要： | 在高频部分，通过用Ｗｅｎｔｚｅｌ—Ｋｒａｍｅｒｓ—Ｂｒｉｌｌｏｕｉｎ—Ｊｅｆｆｅｒｙｓ（ＷＫＢＪ）解作为内场近似，本文证明了有耗非均匀媒质的反射系数在复平面上的轨迹是个圆。根据不同入射角度、不同极化的高频反射系数圆的圆心与半径，可以重建出有耗媒质的部分关键参数。本文方法同时适用于已知复反射系数谱和仅知反射系数振幅情况。文中给出具体重建实例。

| Abstract: | In high fretluency region , the locus of the reflection coefficient of one-dirnensional lossy inhomogeneous medium as a funerion of wave number in the coinplex plane is shown to be a circle by using the WentzelKramers-Brillouin-Jefferys(WKBJ) solution as the approxirnation of insitle field. From the radii and intercepts ofthe circles which are forrned at different incident angles and different polarizmtions , sonle key properties lhat describethe medium can be deduced. This rnethed is applicable either to both the cornplex reflection spectrum or to the amplitude spectrum alone. Examples are given. |
