ABSTRACT:
A three-dimensional holographic array of radio-frequency (RF) diffraction gratings, each of which has lengths of conductive and insulating fluid that are selected and adjusted to provide a desired diffraction effect on incident RF radiation. The three-dimensional array functions analogously to an optical hologram, and is programmable to provide desired refraction and focusing effects on multiple RF incident beams, which may be selectively directed to receivers or, if interferers, ignored. Because the gratings employ conductive and insulating fluids, the array can be reprogrammed in near real time to adapt to changes in the incident RF radiation.
