Abstract
A three-dimensional transmission-line matrix model was developed to simulate the microwave detection of local changes in permeability. The technique can be used to map local nonuniformities in magnetization. Numerical modeling was carried out for frequencies that are commonly used in microwave nondestructive testing (0.8-1 GHz). A comparison between experimental and numerically generated curves is provided. This comparison validated the proposed numerical model.
