Ultrasparse Dielectric Nanowire Grid Polarizers
Ultra-sparse dielectric nanowire grids show strongly polarization-dependent properties and they can 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). Visualization of the interaction between electric field and the nanowire grids are presented.
