Forward and inverse scattering problems in the time domain
An efficient method of solving the 2${1\over 2}$-dimensional electromagnetic forward scattering problem in the time domain is developed, which circumvents the use of three-dimensional arrays to solve the vector wave problem. The method is based on calculating the three-dimensional fields as a summation of Fourier-transformed two-dimensional fields. Each 2D problem is solved via the finite-difference time-domain algorithm. The solution is used to develop a realistic model of the subsurface interface radar.
