Suppressed light transmission through corrugated metal films at normal incidence

Abstract

In the study of light transmission through corrugated metallic film, it has been shown that along with the enhancement of light transmission, suppression may take place at specific values of the period and magnitude of corrugation for normal light incidence. Suppression was found to be due to the interplay between symmetric and assymetric surface plasmon polariton modes at their simultaneous excitation.

Optical properties of metallic nanoparticle arrays on a thin metallic film

“…Ridge-enhanced optical transmission was predicted through thin continuous Ag films, 27,28 while similar structures were reported, also, to suppress light transmission at certain geometries due to the interplay between symmetric and asymmetric surface plasmon-polariton modes. 29 The enhanced light transmission through two-dimensionally corrugated metallic films without holes was confirmed experimentally, 14 while enhanced transmission though metal films can be achieved also by impedance matching at the interface of the metal with the dielectric and no corrugation is required. 30 Despite the fact that impedance matching is a very useful concept, this method is rather difficult to achieve for normally incident radiation.…”

Efficiency enhancement of surface barrier solar cells due to excitation of surface plasmon polaritons

“…In this work, the efficiency of solar cells based on SBH is analyzed in the framework of the diffusion-diode theory using differential formalism for modeling of light propagation through corrugated metal forming SBH. The last problem of periodically texturized metal film transmittance has been considered theoretically in many papers (see, for example, [23][24][25][26]). The essential light transmission suppression has been predicted for symmetric film.…”
