Numerical Estimation of Bending in Holographic Volume Gratings by Means of RCWA and Deep Learning [PDF]

Applied Sciences
In this paper, we introduce a novel approach to model bending phenomena on holographic volume gratings based on Rigorous Coupled Wave Analysis (RCWA), in which the bending as a phase in the dielectric permittivity expansion is introduced, and the Shooting Method (SM) is employed to solve the resulting system of equations.

Diffraction Grating Theory with RCWA or the C Method [PDF]

, 2006
Diffraction gratings are often used in optical metrology. When an electromagnetic wave is incident on a grating, the periodicity of the grating causes a multiplicity of diffraction orders. In many metrology applications one needs to know the diffraction efficiency of these orders. Since the period of a grating is often of the same order of magnitude as

RCWA and FDTD modeling of light emission from internally structured OLEDs [PDF]

Optics Express, 2014
We report on the fabrication and simulation of a green OLED with an Internal Light Extraction (ILE) layer. The optical behavior of these devices is simulated using both Rigorous Coupled Wave Analysis (RCWA) and Finite Difference Time-Domain (FDTD) methods.

Reducing complexity in photonic simulations: ZenScat — an efficient 2D RCWA solver

SoftwareX
We present a comprehensive solver implementation of a 2D Rigorous Coupled Wave Analysis (RCWA), tailored specifically for conformal thin multilayer devices and 2D photonic crystals with arbitrary interface profiles. Unlike traditional diffraction efficiency analysis, our approach emphasizes beam-shaping applications.
