Multi-directional radio frequency electro-magnetic energy deflector

Claim 1

A RETROFLECTOR STRUCTURE FOR ELECTROMAGNETIC ENERGY COMPRISING A SPHERICAL BODY OF MATERIAL HAVING AN INDEX OF REFRACTION FOR SAID ENERGY WHICH IS NON-UNIFORM AND VARIES AS A FUNCTION OF THE POSITION OF THE MATERIAL, SAID FUNCTION BEING SELECTED TO CONTINUOUSLY REFRACT AN INCIDENT RAY AND TURN IT THROUGH AN ANGLE OF APPROXIMATELY 180* AT ITS POINT OF EMERGENCE, SAID BODY HAVING PORTIONS OF ALTERED TRANSMISSION CHARACTERISTICS FOR SAID ELECTROMAGNETIC ENERGY TO PREVENT SAID CONTINUOUS REFRACTION OF CERTAIN OF SAID RAYS IN SAID PORTIONS, SAID PORTIONS INTERCEPTING RAYS PASSING THROUGH A SECTOR OF AT LEAST ONE CENTRAL CROSSSECTION OF SAID BODY, SAID SECTOR BODY ANGULARLY SPACED BY 90* FROM A PART OF SAID CROSS-SECTION NOT CONTAINING SUCH PORTION TO PREVENT SAID CONTINUOUS REFRACTION OF RAYS PASSING THROUGH SAID PORTIONS WHEREBY PART OF RAYS IMPINGING ON SAID BODY OF MATERIAL ARE REFRACTED THROUGH APPROXIMATELY 180*, AND THE REMAINING PART OF SAID IMPINGING RAYS ARE INTERCEPTED BY SAID PORTIONS TO PREVENT THEIR CONTINUOUS REFRACTION THROUGH APPROXIMATELY 180*, SO THAT EMERGENT RAYF SO POLARIZED AS TO INTERFERE WITH OTHER EMERGENT RAYS ARE AT LEAST PARTLY EFFECTIVELY ELIMINATED.
