The advance in nanoplasmonics is oftentimes limited by the availability of electromagnetic analysis tools capable of addressing large, complex realistic systems that encompass multiple wavelength scales. The present work shows that surface integral equation (SIE) method of moments (MoM) formulations, expedited via the multilevel fast multipole algorithm (MLFMA), can effectively model the interaction...
We show experimentally for the first time that free-electron evanescent fields can be amplified by a plasmonic nanolayer in much that same way as optical evanescent fields are amplified in the poor-man's superlens.
