Polarization-Selective Bidirectional Absorption Based on a Bilayer Plasmonic Metasurface
We propose an alignment-free and polarization-selective bidirectional absorber composed of a one-dimensional bilayer Au grating array buried in a silicon nitride spacer. The absorptivity of the designed structure is more than 95% (77%) under normal forward (backward) TM-polarized light incidence, an...
