RADIO FREQUENCY WAVE AND OPTICAL BEAM STEER COMBINATION

摘要

A combination RF and optical beam steerer comprising an optically transparent substrate having first and second major surfaces, the first surface having disposed theron an array of conductive elements associated with a radio frequency beam steerer and the second surface thereof having an array of elements disposed thereon associated with an optical beam steerer. The spacing of the elements in the RF beam steerer are at least ten times the wavelength of the optical energy to be steered by the device so that the RF beams steerer appears to be essentially optically transparent to the optical energy whereas as the array associated with the optical beam steerer is sufficiently closely spaced so as to function as a ground plane for the RF beam steerer.
