A Complex Domain Mapping of the SCN for an Effective PML Implementation in TLM
IEEE Open Journal of Antennas and Propagation, 2020 An improved implementation of the perfectly matched layer (PML) is developed for the Transmission Line Modelling (TLM) method based on a mapping of the symmetrical condensed node (SCN) to an analytically extended geometric space. By mapping the TLM node,

Design of bent photonic crystal fiber supporting a single polarization [PDF]
, 2011 In this work, it is shown that the differential loss between the TE- and TM-polarized fundamental modes in a highly birefringent photonic crystal fiber (PCF) can be enhanced by bending the fiber.

A General Perfectly Matched Layer Model for Hyperbolic-Parabolic Systems [PDF]
, 2009 This paper describes a very general absorbing layer model for hyperbolic-parabolic systems of partial differential equations. For linear systems with constant coefficients it is shown that the model possesses the perfect matching property, i.e., it is a ...

A reflectionless discrete perfectly matched layer [PDF]
Journal of Computational Physics, 2019 Perfectly Matched Layer (PML) is a widely adopted non-reflecting boundary treatment for wave simulations. Reducing numerical reflections from a discretized PML has been a long lasting challenge. This paper presents a new discrete PML for the multi-dimensional scalar wave equation which produces no numerical reflection at all.

Limiting absorption principle and perfectly matched layer method for Dirichlet Laplacians in quasi-cylindrical domains [PDF]
, 2011 We establish a limiting absorption principle for Dirichlet Laplacians in quasi-cylindrical domains. Outside a bounded set these domains can be transformed onto a semi-cylinder by suitable diffeomorphisms.
