Huygens wavefront tracing: A robust alternative to …
http://sepwww.stanford.edu/oldsep/sergey/sepsergey/huygens.pdf
Unlike ray tracing, it is computed by a numerical solution of partial differential equations. We show that the first-order discretization scheme has a remarkably simple interpretation in terms of the Huygens’ principle and propose a Huygens wavefront tracing (from now on referred to as HWT) scheme as a robust alternative to conventional ray ...

Wavefront tracing Ray tracing Full wave Computational electromagnetism Diffraction 1. Introduction The Huygens–Fresnel principle (Section 1.1) is an important principle in the theory of diffraction. The Huygens construction also accounts for refraction, provided wavelets expand with different velocities in media with different refractive indices.

3-D traveltime computation using Huygens wavefront tracing. Traveltime computation is widely used in seismic modeling, imaging, and velocity analysis. The two most commonly used methods are ray tracing and numerical solutions to the eikonal equation. Eikonal solvers are fast and robust but are limited to computing only the first‐arrival ...

The method is inspired by Huygens’ principle, in the sense that it models the wavefront as an array of point sources. The spatial density of points and the power distribution among them are established according to Gauss-Hermite quadrature for Gaussian beams, or adapted quadrature in more general settings.
