Unexpected Strong Optical Absorption in a Free-Standing Optical Thick Transmission Metallic Grating
In this paper, we predict unexpected optical absorption in an optical thick free-standing transmission metallic grating by introducing periodical back grooves into it. The absorption peak could be very high up to 90%. In the structure, the introduced periodical back grooves bring about different ord...
