UNIVERSITAT Open boundary conditions for wave propagation
 

Summary: TECHNISCHE
UNIVERSIT¨AT
WIEN
Open boundary conditions for wave propagation
problems on unbounded domains
Anton ARNOLD
TU Vienna
Institute for Analysis and Scientific Computing
Graz, 12. September 2007
Anton ARNOLD (TU Vienna) Open boundary conditions 1 / 46
Wave propagation in "unbounded domains" ­ applications:
water waves:
shallow water equation, t-dependent wave equation
open / non-reflecting boundary conditions needed
Anton ARNOLD (TU Vienna) Open boundary conditions 2 / 46
fiber-optic cables:
for core diameter < 10µm :
Maxwell equations, 1-way wave equation (Schr¨odinger/parabolic type)
wave propagation mainly in core limit the computational domain
with open BC
