We analyze the enhancement in optical absorption of an absorbing medium when spherical metal nanoparticles are embedded in it. Our analysis uses generalized Mie theory to calculate the absorbed optical power as a function of the distance from the metal nanoparticle. This analysis is used to evaluate the potential of enhancing optical absorption in thin-film solar cells by embedding spherical me...

Abstract In this paper we consider diffusion in a domain Ω containing partially absorbing target M with position and occupation time resetting. The A t is Brownian functional that determines the amount of particle spends over interv...

General relationships are obtained that govern the evolution of a short signal propagating in selectively absorbing medium. The propagation pulse with rectangular envelope, carrier frequency which is close to one spectral absorption lines medium, considered. It shown case shift relative center line, interference primary and response can lead significant oscillations total time. amplitude these ...
