Fast computation of dipole radiation in stratified background using graphics processing unit

Abstract

We present the GPUs computation acceleration for a very recurrent electromagnetic problem which is the calculation of the field radiated by electric dipoles in a multilayer structure (Green's tensor in stratified background), based on the well-known Sommerfeld integrals. Using an optimized parallelization scheme, huge computation acceleration is obtained. Applications of such a work are very broad, especially for the modeling of stratified light emitting devices, or as a building block for the calculation of optical scattering by complex shape structures, when using methods as discrete dipole approximation (DDA) or method of moments (MoM) for example.
