A polarization-dependent perfect absorber with high Q-factors enabled by Tamm phonon polaritons in hyperbolic materials

Abstract

We design a polarization-dependent perfect absorber with high Q-factors enabled by Tamm phonon polaritons in hyperbolic materials.

Adaptive thermally tunable radiative cooling with angle insensitivity using phase-change-material-based metasurface

“…A black-body emitter is a non-resonant broadband emitter with no spectral selectivity. However, manipulating or controlling thermal radiation within a specific wavelength range is a crucial challenge for various applications, such as thermal camouflage, radiative cooling, and energy harvesting [4][5][6][7][8][9][10][11][12]. To achieve the objective of controlling and managing thermal radiation, researchers have explored the use of metamaterials and their 2D analogs, called metasurfaces operating in the infrared spectrum.…”
