Reconfigurable Chiral Metasurface Absorbers Based on Liquid Crystals
We propose a liquid-crystal-based reconfigurable chiral metasurface absorber and numerically investigate its chiro-optical properties. The chiral metasurface absorber consists of a metal–insulator–metal structure with the substrate, which ...

Design and modeling of photonic crystal Absorber by using Gold and graphene films [PDF]
A novel absorber based on a one-dimensional photoniccrystal (PhC) is proposed by combining the absorptionproperty of gold and graphene films. We designed twophotonic crystals consisting of silicon and silicondioxide layers with lattice constants 125 and ...

A Three-Dimensional Dual-Band Terahertz Perfect Absorber as a Highly Sensitive Sensor
Terahertz (THz) absorbers are highly desirable in sensing and detection devices. Herein, we have proposed a 3D dual-band near-perfect absorber that works in the THz regime for sensing applications.
