TL;DR: The polarization insensitivity is demonstrated by analyzing the absorption performance over arbitrary polarization angles, and the ultra-broadband absorption remains more than 80% over a wide incident angle up to 50°, for both transverse electric (TE) and transverse magnetic (TM) modes.

TL;DR: This work presents an efficient polarization conversion device via using a hollow graphene metasurface that can simultaneously realize a series of excellent performances, including the broadband x-to-y cross polarization conversion (CPC) function with near unity polarization conversion ratio (PCR), dual-frequency linear- to-circular polarization Conversion (LTC) function, and highly sensitive polarization conversion function manipulation under wide oblique incidence angle range.

TL;DR: In this paper, a thin semiconductor void resonators meta-surface is theoretically proposed and numerically demonstrated as a novel platform for perfect solar absorber, which exhibits an ultra-broadband perfect absorption in the visible and infrared range.

TL;DR: In this paper, a new type of silicon metasurface, possessing solar full-spectrum anti-reflection and absorption due to the multiple resonances, is proposed.

TL;DR: In this paper, an all-metal meta-surface (AMMS)-based sensor is numerically demonstrated for temperature measurement with high sensitivity in the sub-wavelength scale, based on the sharp plasmonic resonances and the simultaneous use of perfect absorption response, temperature sensing with an ultra-high enhancement factor of 263 for the spectral figure of merit (FOM) factor is obtained.
