Rigorous coupled-wave analysis of liquid crystal polarization gratings
Optics Express, 2020 Several types of liquid crystal polarization gratings (LCPGs) can be achieved depending on their molecular configurations and diffraction properties. We perform detailed numerical studies of these LCPGs based on the rigorous coupled-wave analysis (RCWA) approach.

Global rigorous coupled wave analysis for design of multilayer metasurface absorbers
Optics Express, 2023 In this work, a novel Global NV-ETM RCWA method is proposed to accelerate the optimization of the periodic stepped radar absorbing structure. This method is based on the rigorous coupled-wave analysis (RCWA) utilizing the normal vector field (NV) and enhanced transmittance matrix (ETM) approach.

Artificial dielectric devices for variable polarization compensation at millimeter and submillimeter wavelengths [PDF]
, 2003 Variable polarization compensation has been demonstrated at 100 GHz. The device consists of two interlocking V-groove artificial dielectric gratings that produce a birefringence that varies with the separation distance. A maximum retardance of 74/spl deg/

Effective spectral optical functions of lamellar nanogratings [PDF]
Journal of the European Optical Society-Rapid Publications, 2006 Spectral properties of lamellar sub-wavelength gratings (nanogratings) are described by effective medium approximation (EMA). Analytical spectral formulae for ordinary and extraordinary effective optical functions are derived for nanogratings consisting ...
