Fundamental bounds on transmission through periodically perforated metal screens with experimental validation
Andrei Ludvig-Osipov, Johan Lundgren, Casimir Ehrenborg +5
This paper presents a study of transmission through arrays of periodic sub-wavelength apertures. Fundamental limitations for this phenomenon are formulated as a sum rule, relating…
