Accurate modelling of line-defect photonic crystal waveguides with the RCWA
Frontiers in Optics 2004/Laser Science XXII/Diffractive Optics and Micro-Optics/Optical Fabrication and Testing, 2004By using grating codes, and namely on the RCWA (also called Fourier modal method), we show that non-periodic photonic-crystal devices can be rigorously modelized.

Formulation of the normal vector RCWA for symmetric crossed gratings in symmetric mountings
Journal of the Optical Society of America A, 2010The utilization of symmetries in rigorous coupled wave analysis in order to reduce the matrix sizes and thus the computation time is an appropriate measure for an effective numerical implementation with no loss of accuracy. Another method to improve the convergence is the so-called normal vector method. This method is based on the transformation of the

Application of RCWA method to optoelectronic numerical simulations of 2D nanostructures
The 4th IEEE International NanoElectronics Conference, 2011This paper presents some applications of a new implementation of the Fourier modal method to solve the Maxwell equations in nanostructured optoelectronic solid state devices like solar cells and image sensors. The proposed method is based on an improved and computational efficient T-matrix approach that can be extended to three-dimensional geometries ...

2010 14th International Workshop on Computational Electronics, 2010
This paper presents a new implementation of the Fourier modal method to solve the Maxwell equations in nano-structured solid state devices like solar cells and image sensors. The proposed method is based on an improved T-matrix approach in which the well-known stability problems are solved by adopting multi-precision arithmetic. Examples of application

MoM/RCWA analysis of frequency selective surfaces with inhomogeneous, periodic substrates
2007 18th International Zurich Symposium on Electromagnetic Compatibility, 2007This paper presents a numerical technique for the analysis of a metamaterial that may be considered as a new type of frequency selective surfaces (FSS), consisting of printed metal patches on inhomogeneous, periodic substrates. Such structures are more promising for EMC shielding than common FSS structures because both the effective dielectric ...

Modified RCWA method for studying the resonance diffraction phenomena on metal gratings
2017 IEEE 37th International Conference on Electronics and Nanotechnology (ELNANO), 2017In this work, using the numerical analysis of the diffraction TM-polarized optical waves by metal gratings under resonance of the electromagnetic field was presented. Modified RCWA method has been proposed. Notably, Toeplitz matrices were modified in the system of differential equations.

Fisher-information-guided RCWA metrology with a dielectric binary nanograting
<p dir="ltr">We develop a full-wave Fisher-information framework for diffraction metrology in a dielec- tric binary nanograting using rigorous coupled-wave analysis (RCWA). The structure is a one- dimensional silicon-nitride grating on a silica substrate with two sub-bars per period, enabling simultaneous estimation of a common width perturbation,openaire +1 more source
