Versatile Cross‐Polarization Conversion Chiral Metasurface for Linear and Circular Polarizations
Advanced Optical Materials, 2020 AbstractIn this work, first the necessary conditions for a versatile cross‐polarization conversion meta‐atom that operates both for linear and circular cross polarizations are discussed. Based on these, a versatile chiral metasurface cross‐polarization converter is proposed.

Cascaded Stokes polarization conversion in cubic Raman crystals
Optics Express, 2020 We describe a theoretical approach based on Müller and tensor calculus for predicting the polarization state and gain of cascaded Stokes orders produced under coherent Raman scattering regime conditions. The formulation follows a Markovian-style implementation for F2g-type modes in Raman cubic crystals.

Conversion from linear to circular polarization in FPGA
, 2010 Context: Radio astronomical receivers are now expanding their frequency range to cover large (octave) fractional bandwidths for sensitivity and spectral flexibility, which makes the design of good analogue circular polarizers challenging.

Quantum correlations of twophoton polarization states in the parametric down-conversion process
, 2008 We consider correlation properties of twophoton polarization states in the parametric down-conversion process. In our description of polarization states we take into account the simultaneous presence of colored and white noise in the density matrix ...

Multilayer Full Polarization Conversion Transpolarizing Structures
International Journal of Antennas and Propagation, 2019 In this paper, we propose the design of two perfect multilayered linear transpolarization structures working in transmission. These linear polarization converters are capable to rotate the polarization 90° independently from the direction of the input ...
