The invention disclosed herein uses the metallurgic masks as plasmonic resonance antennas to enhance absorption. Metallurgic masks containing narrow two-dimensional slits provide broadband total optical transmission. At a specific oblique incident angle, these metallurgicmasks enable zero reflection over a wide ...
