摘要: 本文通過建立積分方程并利用矩量法,解決了部分涂覆介質(zhì)導(dǎo)體柱的電磁散射問題。有關(guān)的計算程序成功地實現(xiàn)了通用化,即集導(dǎo)體柱、介質(zhì)柱、全部及部分覆蓋介質(zhì)的導(dǎo)體柱的計算程序為一體。實例計算表明,該程序在計算目標(biāo)雷達(dá)散射特性方面具有較高的實用價值。

Abstract: The scattering properties of the composite cylinders are discussed. Some integral equations are established, then the monent method is used to solve the surface currents under TM and TE polarization separately. After appropriate arrangement, the computer programs have been compiled general use. Finally, some calculation examples are given. The obtained resu-Its are compared with the published data. They are in good agreements. -
