Ultra-Sparse Dielectric Nano-Wire Grid Polarizer

Ultra-sparse dielectric nanowire grids show strongly polarization-dependent properties and can therefore be employed as wideband reflectors [J. W. Yoon et al., Opt. Express 23, 28849-28856 (2015)]. The polarization-, wavelength-, and angle-dependent properties of selected nanowire grids are investigated by using the Fourier modal method (FMM, also known as RCWA). Visualization of the interaction between electric field and the nanowire grids are presented.
