　　　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.

　　　Each unit cell within the Yee lattice contains electric field

　　　components sampled along the edges of the cube and magnetic field

　　　components normal to the faces of the cube (the dual of Fig. 3.1).
