Abstract

The finite element method is used to model the near field of optical components with dimensions on the order of a wavelength. Because open region problems are considered, a conformable local radiation boundary condition is used to truncate the domain and preserve the sparsity of the resulting matrix equation. Diffractive surface examples are presented.
