Design of WideBand Transmission Polarization Converters
2019 Thirteenth International Congress on Artificial Materials for Novel Wave Phenomena (Metamaterials), 2019 A designing tool for wideband transmission polarization converting surfaces is presented. The optimized wideband polarizer comprises several metasurface layers whose unit cell is gradually rotated. The analysis is based on an analytical transmission line model of the multilayer structure with anisotropic elements.

Compact polarization converter in InP-based material
Optics Express, 2005 We present a polarization converter using one-dimensional grating principles. The device is based on slanted slots etched deeply into an InP/InGaAsP heterostructure. Almost complete polarization conversion, with a 14 dB extinction ratio, is observed for a device less than 2 microm long.

Polarization meta-converter for dynamic polarization states shifting with broadband characteristic
Optics Express, 2022 Polarization, as an important property of light, has been widely discussed in modern detecting and radar systems. A polarization converter that can be used to achieve dynamic control is regarded as an excellent alternative for implementing the integrated functionalities of communication and stealth. In this work, we propose a paradigm of meta-converter
