Ultra-broadband nearly perfect absorbers based on graphene-coated lossy metallic nanostructures

Autor: Raha Khosravi, Yashar E. Monfared, Montasir Qasymeh

Publikováno v: Results in Physics, Vol 36, Iss , Pp 105470- (2022)

In this paper, we present a new thin-film broadband nanostructured metamaterial absorber based on a graphene-coated plasmonic lossy metal–insulator–metal. Using the finite element method, we study the absorption properties of the proposed nanostr

Numerical Approach for Studying the Evolution of the Degrees of Coherence of Partially Coherent Beams Propagation through an ABCD Optical System

Autor: Pujuan Ma, Barbora Kacerovská, Raha Khosravi, Chunhao Liang, Jun Zeng, Xiaofeng Peng, Chenkun Mi, Yashar E. Monfared, Yuping Zhang, Fei Wang, Yangjian Cai

Publikováno v: Applied Sciences, Vol 9, Iss 10, p 2084 (2019)

In this paper, we propose a numerical approach to simulate the degree of coherence (DOC) of a partially coherent beam (PCB) with a Schell-model correlator in any transverse plane during propagation. The approach is applicable for PCBs whose initial i
