Imaging Performance of Polarization-Insensitive Metalenses

ACS Photonics, 2019
Metasurfaces have recently emerged as a promising technology to realize flat optical components with customized functionalities. In particular, their application to lenses in various imaging systems is of significant interest. However, a systematic and complete study of the focusing and imaging behavior of metalenses has not yet been conducted. In this

Polarization insensitive dual-band absorber

2017 IEEE 4th International Conference on Knowledge-Based Engineering and Innovation (KBEI), 2017
A simple design of dual-band absorber for WLAN and X-band, is presented. This absorber formed by only an enclosed square ring in a circular split ring and a ground plane, separated by a dielectric layer. It is found that the proposed structure has two distinctive absorption band whose peaks average are about 96% and 97% at 5.6 GHz and 9.6 GHz ...
