Time domain analysis of reflected impulse fields by artificial neural network

The impulse fields reflected from layered medium with losses are analyzed by artificial neural network in time domain directly. The normal incidence of plane wave with Gaussian time form on layered medium is considered. The reflected electromagnetic field is obtained by FDTD method. Initial data for neural network are the values of amplitude of electrical component of reflected field chosen with constant time step. As an example the network is trained to determine the thickness of one of the layers of the medium.
