A simple numerical method for solving diffraction problems was developed. It is based on a multiple scattering approach and a fundamental result in homogenization theory. The method is easily implemented and is efficient for complex inhomogeneous objects.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the proceedings. They include the speaker's narration with video of the slides and animations. Most include full-text papers. Interactive, searchable transcripts and closed captioning are now available for 2018 presentations, with transcripts for prior recordings added daily.
