The Linear Sampling Method in Inverse Electromagnetic Scattering
Author: Fioralba CakoniPublisher: SIAM
ISBN: 0898719402
Category : Mathematics
Languages : en
Pages : 147
Book Description
The linear sampling method is the oldest and most developed of the qualitative methods in inverse scattering theory. It is based on solving a linear integral equation and then using the equation's solution as an indicator function for the determination of the support of the scattering object. This book describes the linear sampling method for a variety of electromagnetic scattering problems. It presents uniqueness theorems and the derivation of various inequalities on the material properties of the scattering object from a knowledge of the far field pattern of the scattered wave.

Book Description
The objective of this research is to study the feasibility of computing electromagnetic wave scattering by objects which are buried or partially buried in a lossy ground. The datas obtained through computer solutions of the related Maxwell's Equations can be applied to detection of plastic land mines, tunnels and natural resources. The method used in this investigation is based on the Unimoment method, a unique hybrid of analytical and numerical methods. The extension of the method to include lossy ground half-space was made possible by the development of special eigenfunctions which include the continuity of the air-ground interface. Results were obtained for scattering by buried body of revolution, buried body of revolution with arbitrary orientation and two-body scattering.

Book Description
Abstract: This dissertation presents a Monte-Carlo multidomain pseudospectral time-domain (MPSTD) algorithm developed for the analysis of scattering from a two dimensional (2D) and three dimensional (3D) object buried below a random rough surface separating two half spaces. In the development, special attention is paid to the 3D computation domain decomposition, PML derivations, filtering technique and subdomain mapping involving the random rough surface as well as the subdomain patching along the rough surface. The Mote-Carlo MPSTD algorithm is then employed to determine the scattering of objects of various shapes and electromagnetic properties; embedded in the lower half space with different permittivity and the roughness of the random rough surface may vary. Sample numerical results are presented, validated, and analyzed. Then, scattering of objects buried in layered structure with random rough surface is studied using MPSTD algorithm. Through the analysis, it is observed that the roughness of the random rough surface and the electromagnetic properties of the lower half space can significantly affect the scattered signature of the buried object.
