Edge diffraction toolbox for Matlab


Matlab toolbox for computing specular reflections and higher-order diffraction, using time- or frequency-domain formulations. Only ideal surfaces are supported, that is, rigid (Neumann) and pressure-release (Dirichlet) surfaces. Iterative formulations (one diffraction order at a time) are used, but also integral equation-based formulations will come.
