金属-电介质复合材料中非局域效应诱导的偏振分光器
Nonlocality-induced polarization beam splitting via metal-dielectric composites
摘要
Abstract
Three kinds of polarization beam splitters are designed by using a simple metal-dielectric multilayered structure with strong nonlocality.It is found that the equal frequency contour for the transverse electric polarization is a small circle when the average permittivity is close to zero.At the same time,the equal frequency contour for the transverse magnetic polarization turns to be two branches of parabolas due to the surface plasmon-induced nonlocal effect.Based on the dramatic difference between dispersions of the two polarizations,three kinds of polarization beam splitters are demonstrated,including the ultrathin ones,which may have important applications in polarization-sensitive absorbers and compact optical devices.关键词
