摘要: 用單色電磁波照射介質(zhì)薄板并測(cè)量其散射場(chǎng),根據(jù)測(cè)得的散射場(chǎng)數(shù)據(jù),可以確定介質(zhì)薄板的電參數(shù)分布。本文給出一種單層和雙層不均勻介質(zhì)薄板的電參數(shù)確定方法,并給出了數(shù)值計(jì)算結(jié)果。

Abstract: The complex parameters of single or double imhomogeneous lossy dielectric slabs can be determined if the slabs is illuminated by a harmonic electromagnetic wave and the scatte-red field is measured. The method of determiniing parameters is described and the numerical re-sults are given. -
