%     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 （充气矩形空腔谐振器） is modeled.  The length width and height of the 
%     cavity are 10.0 cm （x-direction） 4.8 cm （y
