Electromagnetic analysis of large nanoplasmonic assemblies with fast multipole methods

The frontiers in the research field of nanoplasmonics are not seldom restrained by the limits imposed by available electromagnetic analysis tools, which tend to struggle when addressing realistic systems with several-wavelength electric sizes. This work shows that boundary element variational methods, along with the hierarchical spectral compression of the multilevel fast multipole algorithm (MLFMA), can effectively model the interaction of light with large nanoplasmonic assemblies, raising the bar of full-wave simulations in the field of nanoplasmonics to a new level.
