Efficient computation scheme of grating structure using RCWA and FDFD
2011 International Conference on Computational Problem-Solving (ICCP), 2011Rigorous coupled-wave analysis, a classic approach for calculating grating structures, will be very slow in some cases, as involved lots of matrix's eigenvalue problems. The use of finite-difference frequency-domain can avoid eigenvalue problem by introduce a large number of difference calculations.

The RCWA is also an efficient tool for waveguide computational problems
Diffractive Optics and Micro-Optics, 2000We show that, with only a very few modifications, the rigorous coupled wave analysis can be used efficiently for the numerical analysis of waveguide problems. This work extends the domain of applications of grating theories.

Improved diffraction computation with a hybrid C-RCWA-method
SPIE Proceedings, 2009The Rigorous Coupled Wave Approach (RCWA) is acknowledged as a well established diffraction simulation method in electro-magnetic computing. Its two most essential applications in the semiconductor industry are in optical scatterometry and optical lithography simulation.

Application RCWA for studying plasmon resonance under diffraction by metal gratings
2017 IEEE First Ukraine Conference on Electrical and Computer Engineering (UKRCON), 2017A results of numerical analysis RCWA diffraction by metal gratings under plasmon resonance are presented. Numerical experiments show low convergence of traditional RCWA for such types of the resonances of electromagnetic field. Modified RCWA for studying resonance diffraction phenomena on metal gratings was proposed.

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.

Oblique incidence scatterometry for 2D/3D isolation mounts with RCWA and PML
Proceedings of SPIE, 2016In this paper, we examine the sensitivity of scatterometry for the 2D and 3D isolation mounts on the substrate by applying the PML in the RCWA method. We analyze the reflectance from the silicon and resist single mount on the silicon substrates by changing the incident beam angles. First, we show the propagation properties of the electromagnetic fields

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
