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…

On methods to determine bounds on the Q-factor for a given directivity
B. L. G. Jonsson, Shuai Shi, Lei Wang +2
This paper revisit and extend the interesting case of bounds on the Q-factor for a given directivity for a small antenna of arbitrary shape. A higher directivity in a small antenna…
