摘要: 本文提出一種解非均勻介質(zhì)體電磁散射問題的新方法。由測量到的介質(zhì)體外的散射場,按照遞推關(guān)系,可以求出全部介質(zhì)體內(nèi)的場分布。文章詳細地推導了介質(zhì)體內(nèi)場分布的遞推關(guān)系,并給出了計算機模擬計算的結(jié)果。

Abstract: A new approach to the EM scattering problem of an inhomogeneous lossy dielectric body is proposed. It is shown that the entire interier electric field distribution can be obtained from the measured exterier field distribution by simple recurrence relations. Detailed derivations of those recurrence relations for the field distribution inside the scattering body are presented, and the results obtained by computer simulations are given. -
