A direction preserving discretization for computing phase-space densities
David J. Chappell, Jonathan J. Crofts, Martin Richter +1
Ray flow methods are an efficient tool to estimate vibro-acoustic or electromagnetic energy transport in complex domains at high-frequencies. Here, a Petrov-Galerkin discretization…

Transfer operator approach to ray-tracing in circular domains
J Slipantschuk, M Richter, D J Chappell +3
The computation of wave-energy distributions in the mid-to-high frequency regime can be reduced to ray-tracing calculations. Solving the ray-tracing problem in terms of an operator…
