Optimizing perfectly matched layers in discrete contexts
International Journal for Numerical Methods in Engineering, 2014 SUMMARYPerfectly matched layers (PMLs) are widely used for the numerical simulation of wave‐like problems defined on large or infinite spatial domains. However, for both time‐dependent and time‐harmonic cases, their performance critically depends on the so‐called absorption function.

CALCULATION OF ELECTROMAGNETIC FIELDS IN INHOMOGENEOUS MEDIA FOR SELECTION OF PROTECTIVE COATINGS
Electrical engineering & Electromechanics, 2019 The aim of the work is to develop a method for high-frequency EMFs calculation in terms of the modified vector potential and to use it for choice of the parameters of the layered absorbing coatings that provide effective absorption of radio wave ...

Distributed Etched Diffraction Grating Demultiplexer With Flat-Top Insertion Loss Envelope
IEEE Photonics Journal, 2011 It is numerically shown that incorporation of a distributed Bragg reflector at the facets of an etched diffraction grating (EDG) can be used to tailor the output spectral response of the device.
