Study of Effect of Seam on Wire-Grid Polarizer Efficiency Using Rigorous Coupled-Wave Analysis

Abstract

In this paper, the effects of vibrations at high frequencies onto a freely falling two-body system in Schwarzschild spacetime are investigated. As reference motion of the same system without vibrations, a circular orbit around the central body is considered. The vibrations induce a perturbation on this motion, whose period is close to the orbital period, in agreement with the simpler situation of the Shirokov effect [1]. In general relativity, the amplitude of the perturbation is dominated by high-velocity effects, which grow linearly in the radius r of the circular orbit, while the leading term surviving the Newtonian limit decays as 1/r. Thus, even for very large radii a significant difference between Newtonian physics and general relativity is found. We give an estimate of this effect for some molecular vibrations of a system orbiting around the Earth.

High-performance wire-grid polarizers using jet and Flash™ imprint lithography

“…24 To model WGPs containing defects in different sizes and densities, 3-D modeling with a periodic boundary condition along the grating direction (x-axis) and a perfectly matched layers boundary condition for the y and z direction was applied. In the graphs shown below, the Al line size and pitch were set to 50 and 100 nm, respectively.…”

“…Moreover, the optical properties of this structure under the TM wave incidence are also analyzed and discussed. Based on the rigorous coupled wave analysis method (RCWA) 20 , the calculated efficiency of each diffraction order is determined from the time-averaged Poynting vector in the z-direction, normalized to that of the incident wave. The directional hemispherical reflectance/transmittance is the summation of the efficiencies of all reflected/transmitted orders.…”
