Abstract
the high-frequency Brewster angle, is discussed
as a possible simulator for placing fast-rising pulsed electromagnetic fields
over a ground surface. The reflection of a rectangular pulse at the.highfrequency
Brewster angle is calculated, showing that for pulse widths less
than the relaxation time of the ground, the reflection amplitude is small
compared to the incident amplitude. ,This type of simulator may be appropriate
for simulation tests involving low ground conductivities.
