JCMsuite: The Complete Solution

Light scattering

Problem Class: Optical Scattering

JCMsuite contains the module JCMharmony for the solution of optical scattering problems. Scattering problems are problems, where the refractive index geometry of the objects are given, incident waves as well as (possibly) interior sources are known and the response of the structure in terms of reflected, refracted and diffracted waves has to be computed. The left figure sketches the response of a micro lens subject to waves incident from the left and the right figure shows an actual simulation of a micro lens with antireflection coating.

Problem Class: Optical Scattering - Mathematial Definition

To compute scattering solutions, we solve the time-harmonic Maxwell's curl-curl equation

for given sources J (current densities and dipols) and incident fields. In modeling scattering problems one considers the field exterior to the scattering object as superposition of s ource and scattered fields. Since the scattered fields move away from the object they have to satisfy a radiation condition. In JCMsuite we implemented a mathematical rigorous perfectly matched layer (PML) based on an adaptive and self-controlled algorithm.
