TL;DR: It is shown that a single rectangular hole in a metallic film exhibits transmission resonances that appear near the cutoff wavelength of the hole waveguide, and this resonant transmission process is accompanied by a huge enhancement of the electric field at both entrance and exit interfaces of thehole.

TL;DR: It is demonstrated that textured closed surfaces, i.e., particles made of perfect electric conductors (PECs), are able to support localized electromagnetic resonances with properties resembling those of localized surface plasmons (LSPs) in the optical regime and a metamaterial approach is presented that captures the basic ingredients of their electromagnetic response.

TL;DR: It is shown how both the subwavelength confinement associated with surface plasmons and the one-dimensional character of plasmonic waveguides can be exploited to enhance the coupling between quantum emitters.

TL;DR: In this article, the waveguid-ing elements are based on plasmonic and metamaterial notions and consist of an easy-to-manufacture periodic chain of metallic box-shaped elements protruding out of a metallic surface.
