INHOMOGENEOUS MAGNETIC MEDIA: WAVE PROPAGATION AND MAGNETIC PERMEABILITY RECONSTRUCTION

Wave Propagation and Blocking in Inhomogeneous Media

Wave propagation governed by reaction-diffusion equations in homogeneous media has been studied extensively, and initiation and propagation are well understood in scalar equations such as Fisher’s equation and the bistable equation. However, in many biological applications the medium is inhomogeneous, and in one space dimension a typical model is a series of cells, within each of which the dyna...

Modeling of wave propagation in inhomogeneous media.

We present a methodology providing a new perspective on modeling and inversion of wave propagation satisfying time-reversal invariance and reciprocity in generally inhomogeneous media. The approach relies on a representation theorem of the wave equation to express the Green function between points in the interior as an integral over the response in those points due to sources on a surface surro...

Traveling Pulses and Wave Propagation Failure in Inhomogeneous Neural Media

We use averaging and homogenization theory to study the propagation of traveling pulses in an inhomogeneous excitable neural network. The network is modeled in terms of a nonlocal integrodifferential equation, in which the integral kernel represents the spatial distribution of synaptic weights. We show how a spatially periodic modulation of homogeneous synaptic connections leads to an effective...

Tensor Product Derivative Matching for Wave Propagation in Inhomogeneous Media

We propose a tensor product derivative matching (TPDM) method to restore the accuracy of high-order finite difference time-domain (FDTD) schemes of computational electromagnetics (CEM) Figure 4 Measurement results of reverse-transmission gain and outputreturn loss for GaInP/GaAs HBT wideband amplifiers with and without emitter peaking Figure 5 Measured ZT and Z21 of GaInP/GaAs HBT wideband ampl...
