Nanotechnology is rated as a key technology of the 21st century. In the field of nano-optics already at present, state-of-the-art scientific experiments and industrial applications exhibit nanometer to sub-nanometer design tolerances. This motivates the development and application of fast and accurate simulation tools for these fields or electromagnetic (EM) field.
