We report that a metal-dielectric-metal cavity with a perforated top metallic filn shows a remarkable polarizationselective collimation effect through reflection on the perforated film.According to simulations,such plasmonic cavities can achieve nearly perfect absorption (R＜1.5％) of a transverse magnetic (TM) wave at an optimized incident angle while nearly perfect reflection (R～100％) at normal incidence.A very wide incident angle range (approximately 15°-65°) is found to exhibit a high absorption ratio exceeding over 70％.In contrast,for a transverse electric (TE) wave,the plasmonic cavities remain highly reflective (R～100％) regardless of the incident angles.We elucidate that this polarization- and angle-dependent behavior arises from an even-order (N =2) horizontal Fabry-Perot (FP) resonant mode inside the plasmonic cavity.This effect may find potential applications for angle filtering of polarized divergent light beams in optics.
