GPU-accelerated simulation of the superresolution capabilities of dielectric microspheres using the Differential Method

Rigorous simulations of three-dimensional structures containing different shapes and materials are often too extensive for being performed with regular hardware. We present an application of the Differential Method which is able to perform rigorous simulation of three dimensional microspheres, which are placed with an air-gap over a structured region. An application of GPU-accelerated calculations as well as changes in the approach to the integration algorithms provide a considerable speedup in calculation time. This enables an investigation of the already shown, but until now not reasonably computable super resolution capababilities of microspheres.
