Ultra-narrow multi-band polarization-insensitive plasmonic perfect absorber for sensing
Nanotechnology, 2020We theoretically propose a simple ultra-narrow multi-band perfect absorber for sensing applications. The perfect absorber consists of periodically arranged metallic nanodisks etched with regular prismatic holes standing on the dielectric-metal bi-layer ...

Polarization-insensitive all-optical demultiplexing system
Proceedings of 1996 Canadian Conference on Electrical and Computer Engineering, 2002A novel all-optical demultiplexing system which is insensitive to the state of polarization of the input signals as well as to their drift in polarization is simulated. The technique employs a modified nonlinear optical loop mirror configuration to demultiplex 50 GHz pulse train into 10 GHz. The gain of an erbium-doped fiber amplifier is varied between

Polarization insensitive metamaterial absorber for energy harvesting
2015 27th International Conference on Microelectronics (ICM), 2015This paper presents the design of a polarization insensitive microwave absorber based on metamaterial for electromagnetic energy harvesting. The unit cell of the metamaterial consists of eight-fold rotational symmetric electric resonator printed on FR4 substrate with a ground plane to realize both electric and magnetic resonances to achieve efficient ...
