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...
متن کاملPropagation of Reactions in Inhomogeneous Media
Consider reaction-diffusion equation ut = ∆u+f(x, u) with x ∈ R and general inhomogeneous ignition reaction f ≥ 0 vanishing at u = 0, 1. Typical solutions 0 ≤ u ≤ 1 transition from 0 to 1 as time progresses, and we study them in the region where this transition occurs. Under fairly general qualitative hypotheses on f we show that in dimensions d ≤ 3, the Hausdorff distance of the super-level se...
متن کاملWave 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...
متن کاملFundamental-mode laser-beam propagation in optically inhomogeneous electrochemical media with chemical species concentration gradients.
Solutions to Maxwell's wave equation have been derived for the propagation of the fundamental (Gaussian) mode of a laser beam in a fluid electrolyte which is in contact with an active electrode. An electrochemical or photoelectrochemical reaction at the electrolyte-electrode interface is assumed to generate a concentration gradient of the product in the electrolyte, which results in an inhomoge...
متن کاملPropagation of a finite optical beam in an inhomogeneous medium.
The first part of this paper is devoted to extending the Huygens-Fresnel principle to a medium that exhibits a spatial (but not temporal) variation in index of refraction. Utilizing a reciprocity theorem for a monochromatic disturbance in a weakly inhomogeneous medium, it is shown that the secondary wave-front will be determined by the envelope of spherical wavelets from the primary wavefront, ...
