A wideband quasi-optical millimeter-wave resonator achieves a wideband frency operation by using a variable dielectric constant photoconducting lens in a Fabry-Perot resonator. Changing the dielectric constant of the lens creates an associated change in the resonant frequency for a given axial mode.

Wideband quasi-optical millimeter-wave resonator

This invention is a beam rider system and method that utilizes polarization-agile millimeter beams. Information is spatially encoded in the beams by varying the rate of rotation of the linearly polarized vector of the beams. In one embodiment, information is encoded on a beam that is nutated around a centerline flight path of a missile. In another embodiment, information is encoded on four parallel beams that form a centerline which is the intended flight path of the missile. Receiver means in the flying missile receive and decode information from the beams and use this decoded information to guide the missile to a target.
