Optical Cages

arXiv:1807.05915 · doi:10.1016/j.omx.2019.100008

Abstract

We examine array of metal-mesh frameworks for their wide-band absorption. These take the form of quasi-crystal optical cages. An array of cages tends to focus the incoming radiation within each framework. An array of cage-within-cage funnels the radiation from the outer cage to its inner core even further.
