We will give a brief overview of multiscale modeling for wave equation
problems and then focus on two techniques. One is an energy conserving
DG method for time domain and the other is a new a new sweeping
preconditioner for frequency domain simulation. The latter is resulting
in a computational procedure that essentially scales linearly even in
the high frequency regime.
