Patent ID: 7227684

Claim:
A radiation polarizer for maximizing a transmission of a first polarization state while minimizing a reflection of the first polarization state, and for minimizing a transmission for an orthogonal second polarization state while maximizing a reflection of the second polarization state, said polarizer comprising: a substrate; at least one anti-reflection coating layer communicatively coupled to said substrate; and at least two nanostructures communicatively coupled to said at least one anti-reflection coating layer thereby forming a layer of nanostructures; said at least two nanostructures each including a metallic and dielectric combination, said metallic and dielectric of said combination being located adjacent each other, said metallic having a short surface and a long surface, said dielectric extending only partially along said long surface of said metallic; wherein said nanostructure layer polarises the radiation, and wherein the radiation has a wavelength in a range of about 250 nm to less than 30 microns.
