摘要/Abstract

摘要： 在非均匀介质电磁散射、逆散射等领域中,经常需要快速、精确地计算汉克尔变换来完成高效率的正演计算。针对任意平面分层的非均匀介质情形,以偶极子激励为例,应用快速傅里叶变换(FFT)来完成汉克尔变换计算。

Abstract: For electromagnetic scattering and inverse scattering problem in inhomogeneous media,calculating Hankel transform rapidly,accurately is often required in order to perform efficient forward calculation.Here,fast Fourier transform is used to finish the calculation of Hankel transform in case of a dipole exciting in arbitrary planar layer-media.

Key words: planar layer-media, hankel transform, forward computation, Fast Fourier Transform(FFT)
