Modelling teleseismic waves in dipping anisotropic structures

Propagation of Electromagnetic Waves in Anisotropic Photonic Structures

Nowadays layered photonic structures (LPSs) are key of optoelectronic and microwave devices such as, phased-array antennas, microcavities and mirrors [1,2], filters of xWDM systems [3], waveguide structures, photodetectors, sensors and others. In case of active devices the layered structures are usually used in form of superlattices [4-6], multiple quantum wells [7,8] and asymmetric multiple qu...

2.5-D Time-Domain Finite-Difference Modelling of Teleseismic Body Waves

Nondiffracting waves in anisotropic media.

Recently the physics of ballistic phonon propagation in anisotropic crystals has been studied with new phonon-imaging methods. In this paper we consider nondiffracting waves that can propagate in anisotropic crystals and analyze their properties that emerge specifically due to the anisotropy. We further present a detailed generation and detection scheme for the experimental verification of the ...

Modelling linear wave transformation induced by dissipative structures—Regular waves

A numerical model of the modified time-independent mild-slope equation for linear waves over a rapidly changing finite porous bed is presented. In this solution the reflection and phase coefficient shift are solved implicitly. Boundaries are assumed to be open, partially reflecting, or fully absorbing through the second-order parabolic approximation. Discretisation of the governing equation and...

Structures in Anisotropic Multilayered Media

Applying the concept of spectral domain representation, the moment method or the point-matching procedure and Green's function theory, a unified approach for the computation of the static capacitance of single, coupled and comb-like metallic structures in anisotropic multilayered media is presented. The media can be electrically shielded on one or both sides. The geometry of the parallel strips...
