Perfectly matched layers for two-dimensional open waveguides: Semi-infinite Laguerre-based and unbounded-function finite-thickness formulations

This paper presents an alternative finite element method for the computation of trapped and leaky waves in two-dimensional elastic open waveguides, relying on a Laguerre spectral representation of perfectly matched layers (PMLs). Using a Gauss-Radau-Laguerre quadrature rule, the...
