A geometrical optics framework for analyzing attenuation in multimode waveguides using internal reflection count. Includes analytical models, Monte Carlo simulations, and FDTD validation.
C++17 repository for the didactic and reproducible reconstruction of Marcatili’s 1969 dielectric rectangular waveguide and directional coupler models, connecting the original article, technical documentation, validation workflows, and numerical implementations for modes, dispersion, coupling, and figure-by-figure reproduction.
Reprodução didática em C++17 do artigo de Koshiba e Inoue (1992), aplicando o método dos elementos finitos com elementos de aresta triangulares à análise de guias de onda de micro-ondas e ópticos, com foco em autovalores, constante de propagação, modos guiados e eliminação de soluções espúrias.
