Pulsed Excitation

Compatibility:

For pulsed excitations the incident field has the form:

FDTD - Equation 53

where

FDTD - Equation 54

is the pulse envelope function, toff is the time offset and t0 is the pulse width
parameter.

For pulsed excitations the time stepping continues until the desired late-time pulse
response is observed at the field points of interest.
