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 ...

On the design of polarization‐insensitive semiconductor optical amplifiers
Microwave and Optical Technology Letters, 2002AbstractWe have used the 4 × 4 Luttinger–Kohn Hamiltonian to analyse the presence of delta‐strain in quantum well on the polarization properties of semiconductor optical amplifiers. The analysis is performed for a 1.55 μm InGaAsP/InP lattice matched system grown in the [001] direction with and without the electrostatic effects of the carrier charges ...

Polarization insensitive, broadband terahertz metamaterial absorber
Optics Letters, 2011We present the simulation, implementation, and measurement of a polarization insensitive broadband resonant terahertz metamaterial absorber. By stacking metal-insulator layers with differing structural dimensions, three closely positioned resonant peaks are merged into one broadband absorption spectrum.

A polarization-insensitive optical amplifier consisting of two semiconductor laser amplifiers and a polarization-insensitive isolator in series is presented. The isolator not only eliminates the cavity coupling between two amplifiers, but also rotates polarized forward light by 90 degrees . Experiments demonstrate the elimination of cavity coupling and

Imaging Performance of Polarization-Insensitive Metalenses
ACS Photonics, 2019Metasurfaces 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), 2017A 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 ...
