An ultra-broadband solar absorber based on α-GST/Fe metamaterials from visible light to mid-infrared

Abstract

In this work, an ultra-broadband (4597 nm) and high absorption rate (98.5%) absorber based on Fe and phase changing materials is realized.

Multi-band perfect absorber based on an elliptical cavity coupled with an elliptical metal nanorod

“…Metamaterials show some optical properties that differ from those of natural materials. [1][2][3][4][5] The resonance wavelength can be customized arbitrarily in microwave, terahertz, and near-infrared regions. [6][7][8] Metamaterialbased absorbers (MBAs) have attracted great interest due to their scalable properties and a wide variety of potential applications, such as solar and thermophotovoltaic energy conversion, cloaking, sensors, and thermal emitters.…”
