Simulation of a waveguide filter using wavelet-based numerical homogenization
We apply wavelet-based numerical homogenization to the simulation of an optical waveguide filter. We use the method to derive approximate one-dimensional models and subgrid models of the filter. Numerical examples of the technique are presented, and the computational gains are investigated. (C) 2001 Academic Press.
