% This MATLAB M-file implements the finite-difference time-domain
% solution of Maxwell’s curl equations over a three-dimensional
% Cartesian space lattice comprised of uniform cubic grid cells.
%
% To illustrate the algorithm, an air-filled rectangular cavity
% resonator is modeled. The length, width, and height of the
% cavity are 10.0 cm (x-direction), 4.8 cm (y-direction), and
% 2.0 cm (z-direction), respectively.
%
% The computational domain is truncated using PEC boundary
% conditions:
% ex(i,j,k)=0 on the j=1, j=jb, k=1, and k=kb planes
% ey(i,j,k)=0 on the i=1, i=ib, k=1, and k=kb planes
% ez(i,j,k)=0 on the i=1, i=ib, j=1, and j=jb planes
% These PEC boundaries form the outer lossless walls of the cavity.
%
% The cavity is excited by an additive current source oriented
% along the z-direction. The source waveform is a differentiated
% Gaussian pulse given by
% J(t)=-J0*(t-t0)*exp(-(t-t0)^2/tau^2),
% where tau=50 ps. The FWHM spectral bandwidth of this zero-dc-
% content pulse is approximately 7 GHz. The grid resolution
% (dx = 2 mm) was chosen to provide at least 10 samples per
% wavelength up through 15 GHz.
