% The dimensions of the computational domain are 8.2 cm
% (x-direction) 3.4 cm (y-direction) and 3.2 cm (z-direction).
% The grid is terminated with UPML absorbing boundary conditions.

% An electric current source comprised of two collinear Jz components
% (realizing a Hertzian dipole) excites a radially propagating wave.
% The current source is located in the center of the grid. 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
