Numerical subgrid scale models for the Yee scheme
(English)Manuscript (preprint) (Other academic)
The Yee scheme is a very common and practical algorithm for the simulation of wave propagation on uniform grids. We develop numerical subgrid scale models in order to incorporate effects of obstacles and holes that are smaller than the grid spacing. The models are based on pre-computing at the microscale, and are thus including the effect of the detailed small scale shape. Numerical examples in 1D, 2D and 3D are given.
