Rigorous coupled-wave analysis (RCWA) is a semi-analytical method in computational electromagnetics that is most typically applied to solve scattering from periodic dielectric structures. It is a Fourier-space method so devices and fields are represented as a sum of spatial harmonics. See more The method is based on Floquet's theorem that the solutions of periodic differential equations can be expanded with Floquet functions (or sometimes referred as Bloch wave, especially in solid-state physics community). A … See more Boundary conditions must be enforced at the interfaces between all the layers. When many layers are used, this becomes too large to solve simultaneously. Instead, we borrow from network theory and calculate scattering matrices. This lets us solve the boundary conditions … See more Being a Fourier-space method it suffers several drawbacks. Gibbs phenomenon is particularly severe for devices with high dielectric contrast. Truncating the number of spatial harmonics can also slow convergence and techniques like fast Fourier factorization … See more RCWA analysis applied to a polarized broadband reflectometry measurement is used within the semiconductor power device industry … See more • RODIS • EMpy • MRCWA • S4 • Unigit (RCWA, Rayleigh–Fourier & C-method) • RawDog See more incoming agentur barcelonaWebMay 31, 2024 · Later chapters highlight spectral techniques and RCWA as applied to the analysis of dynamic wave-mixing in PR materials with induced transmission and reflection … incheon to busanWebApr 8, 2024 · RCWA calculates the intensity and polarization characteristics of the various diffracted orders (zeroth order and higher orders).
