THE INVERSE ELECTROMAGNETIC SCATTERING OF INHOMOGENEOUS DIELECTRIC THIN TUBES

摘要: 本文采用傅里葉級數(shù)展開的方法,處理截面為窄圓環(huán)的二維損耗介質(zhì)體的電磁逆散射問題,根據(jù)介質(zhì)體的散射場解析地表達出它的電參數(shù)。模擬計算得到滿意的結果。Abstract: By using the method of Fourier series expansion, the inverse electromagnetic scattering problem of a 2-dimensional lossy dielectric body, of which the cross section is a narrow annulus, is studied. The analytic expressions of the electric parameters of a dielectric body are given in terms of the outside scattered field. And the simulative computing results are satisfactory.
