Field Inside Component Analyzer: FMM
Abstract
The Field Inside Component Analyzer: FMM allows the user to visualize and investigate the distribution of the electromagnetic field inside micro- and nanostructures. For this purpose, the field inside the periodic structure (transmissive or reflective, dielectric or metallic) is calculated with the Fourier modal method/rigorous coupled wave analysis (FMM/RCWA). It is also possible to specify which part of the field should be visualized: either forward modes, backward modes or both together.
