An electromagnetic radiation interface is provided that is suitable for
use with radio wave frequencies. A surface is provided with a plurality
of electrically conductive bristles. A corresponding plurality of
termination sections are provided so that each bristle is terminated with
a termination section. The termination section may comprise one or more
different termination packages for operating on received electromagnetic
radiation and/or producing desired reflections and transmissions. In one
embodiment, switches and termination packages may be implemented within
integrated circuits wherein the switches may be utilized to switch
between different termination packages. The termination packages may
include selected fixed reactances and/or modulators designed to produce
desired reflections, e.g., Doppler effects to make it appear the surface
of the interface is moving a speed different than the actual speed.
