TL;DR: In this paper, an ultra-wideband polarization conversion metasurface is designed using a double-head arrow structure and further demonstrated both numerically and experimentally both in the microwave regime.

TL;DR: This work designs a triple‐band absorber using the REACTIVE method, where a deep learning model computes the metasurface structure automatically through inputting the desired absorption rate.

TL;DR: In this paper, a new strategy was proposed to tailor the temperature region between the temperature corresponding to the maximum dielectric permittivity and the Burns temperature (TB) of relaxor ferroelectrics to room temperature via composition optimization, to explore lead-free bulk ceramics with high comprehensive energy storage properties.

TL;DR: In this paper, a 2D phase gradient metasurface (PGM) was designed using a square combination of 49 split-ring subunit cells to provide additional wave-vectors along the two in-plane directions simultaneously, leading to either surface wave conversion, deflected reflection, or diffuse reflection.

TL;DR: In this article, a bi-layered linear-to-circular (LTC) polarization conversion metasurface operating in 11.4-14.3 GHz is designed and fabricated, which is composed of two layers of metallic pattern arrays separated by a 1.5mm-thick dielectric spacer.
