* ``f8`` is phi which defines the azimuthal propagation angle (degrees) of the incident plane wave. * ``f8`` is phi which defines the azimuthal propagation angle (degrees) of the incident plane wave.

* ``f10 f11`` are optional parameters. ``f10`` is a time delay in starting the excitation of the transmission line. ``f11`` is a time to remove the excitation of the transmission line. If the time window is longer than the excitation of the transmission line removal time then the excitation of the transmission line will stop after the excitation of the transmission line removal time. If the excitation of the transmission line removal time is longer than the time window then the excitation of the transmission line will be active for the entire time window. If ``f10 f11`` are omitted the excitation of the transmission line will start at the beginning of time window and stop at the end of the time window. * ``f10 f11`` are optional parameters. ``f10`` is a time delay in starting the excitation of the discrete plane wave. ``f11`` is a time to remove the excitation of the discrete plane wave.
