A Broadband Biosensor Using Graphene-Metasurface Based Cross-Polarization Converter
IEEE Sensors Journal, 2022We present the design and analysis of a graphene metasurface-based cross polarization converter operating within the terahertz gap for detecting biomolecules over a broad spectral range, taking the SARS-CoV-2 virus as a specific example.

Efficient polarization converter for projection displays
Applied Optics, 1997In the waveguiding limit, a twisted nematic liquid crystal cell behaves as an achromatic polarization rotator. We propose and demonstrate the application of such a polarization rotator to convert unpolarized light into linearly polarized light with almost 100% efficiency.

A wave polarization converter for circular polarization
IEEE Transactions on Antennas and Propagation, 1963A linearly polarized wave may be converted to a circularly polarized wave by means of a panel which provides 90\deg difference in transmission phase between two crossed linear components. This phase difference is obtained over a wide frequency band by means of thin sheets containing both inductive and capacitive shunt susceptance.

A W-Band Polarization Converter and Isolator
IEEE Transactions on Antennas and Propagation, 2007A 95-GHz printed low-loss linear-to-circular polarizer is designed as a component of an active direct-detection millimeter-wave imaging system. The periodic printed grid structure presents different reactances to the TE and TM polarizations, resulting in equal amplitude and phase quadrature upon transmission through four parallel grids.

Optical element converting linear polarization into circular-tangential polarization
Applied Optics, 1995A new optical element capable of converting linear polarization into circular-tangential polarization (i.e., the electric vector is along the tangential direction to a circle) is proposed and demonstrated. The conversion characteristics of the fabricated element are evaluated, and the magnitude of aberration produced by the element is shown to be ...
