Dipole excitation of surface plasmon on a conducting sheet: finite element approximation and validation

, 2017
We formulate and validate a finite element approach to the propagation of a slowly decaying electromagnetic wave, called surface plasmon-polariton, excited along a conducting sheet, e.g., a single-layer graphene sheet, by an electric Hertzian dipole.

Perfectly matched layers in transmission lines

, 2003
The field distribution at the ports of the transmission line structure is computed by applying Maxwell's equations to the structure and solving an eigenvalue problem. The high dimensional sparse system matrix is complex in the presence of losses and Perfectly Matched Layer.

A Novel Dimensionally Normalized Framework of Maxwell’s Equations for PML-FDTD Applications

IEEE Access
In this study, a novel framework for dimensionally normalized Maxwell’s equations which is suitable for finite difference time domain (FDTD) simulations is presented, where the physical dimensions of electric (E) and magnetic (H) are aligned as ...

Efficient PML for the wave equation [PDF]

, 2009
In the last decade, the perfectly matched layer (PML) approach has proved a flexible and accurate method for the simulation of waves in unbounded media. Most PML formulations, however, usually require wave equations stated in their standard second-order ...

Implementation of PMDL and DRM in OpenSees for Soil-Structure Interaction Analysis

Applied Sciences
It is widely acknowledged that the effects of soil-structure interaction (SSI) can have substantial implications during periods of intense seismic activity; therefore, accurate quantification of these effects is of paramount importance in the design of ...

An absorbing boundary formulation for the stratified, linearized, ideal MHD equations based on an unsplit, convolutional perfectly matched layer

, 2010
Perfectly matched layers are a very efficient and accurate way to absorb waves in media. We present a stable convolutional unsplit perfectly matched formulation designed for the linearized stratified Euler equations.
