Patent ID: 7633425

Claim:
An active denial system, comprising: a gyrotron configured to emit an incident wave beam having an emitted polarization substantially similar to a generated polarization; a housing configured to couple to the gyrotron, wherein the housing is configured to selectively rotate about a principal axis of the gyrotron, wherein the housing is further configured to couple to a selectively rotatable mount; and a plurality of reflective surfaces configured to couple to the housing, wherein the plurality of reflective surfaces is configured for alignment in a waveguide, wherein a first reflective surface from the plurality of reflective surfaces comprises a substantially paraboloidal reflective surface, wherein a second reflective surface from the plurality of reflective surfaces is aligned between the first reflective surface and a third reflective surface along the waveguide, wherein the second reflective surface includes a mode convening substantially corrugated reflective surface, wherein the third reflective surface from the plurality of reflective surfaces comprises a substantially paraboloidal reflective surface, wherein the ratio of the focal length of the first reflective surface to the focal length of the third reflective surface corresponds to sin (β), where β is an angle of incidence of the second reflective surface, wherein a fourth reflective surfaces from the plurality of reflective surfaces is configured to couple with the selectively rotatable mount to selectively direct an incident wave beam to an antenna, wherein the housing further comprises a radome disposed between the waveguide and the antenna, and wherein the antenna is configured to direct the incident wave beam to a target.
