Linear Back Projection (LBP) algorithm, Landweber algorithm and Levenberg-Marquardt (LM) algorithm are three of the popular algorithms used in image reconstruction of Electromagnetic Tomography (EMT). Starting from the non-linear mathematical equation and using Finite Element Method (FEM), a new kind of non-linear algorithm is found with better reconstruction result than the former algorithms.
In this paper, a novel method for solving an inverse problem of electromagnetic tomography is given and a reconstruction algorithm is proposed. Firstly, the simplified sensing model is derived on the basis of a reasonable assumption about media layer in the sensor system. By using a Green’s function method, the solution of the electromagnetic equations of the simplified model which can be classified...
