A Spectral Inverse Scattering Technique with Series-Expanded Field in Dirlectric Object

유전체 내의 전계를 급수전개로 표시한 모멘트 방법을 적용한 파수영역의 역산란 방법

A spectral inversion scheme, based on the moment-method procudure with series-expanded field within each cell by dividing the dielectric object into a small number os rectangular cells with large area, is developed to regularize the ill-posedness inherent in inverse scattering problems. One of the interesting features on the presented scheme is that the relative dielectric constant may be obtained by averaging over each cell. This averaging is expected to play an important role in regularizing the high-frequency effect due to noise.
