Beaming and enhanced transmission through a subwavelength aperture via epsilon-near-zero media
Abstract We numerically validate and experimentally realize considerable funneling of electromagnetic energy through a subwavelength aperture that is covered with an epsilon-near-zero metamaterial (ENZ). The epsilon-near-zero metamaterial is composed of two layers of metasurfaces and operates at mic...
