R. Gruschinski, G. Nimtz, A.A. Stahlhofen
TL;DR
This study demonstrates that nano-metal films can induce a resonance-like enhancement of the Goos-Haenchen shift for TE polarized microwaves, especially when the sheet resistance matches vacuum impedance.
Contribution
It reveals a resonance-like enhancement of the GHS caused by nano-metal films at specific sheet resistances, a novel finding in microwave optics.
Findings
Resonance-like GHS enhancement near vacuum impedance
Weak influence of metal films on TM wave GHS
Experimental validation with microwaves
Abstract
The influence of nano-metal films on the Goos-Haenchen shift (GHS) is investigated. The films deposited at the total reflecting surface of a perspex prism/air have a sheet resistance varying between Z = 25 and 3 000 Ohm. A resonance-like enhancement of the shift and of the absorption is found for TE polarized waves, when the sheet resistance approaches the value of the vacuum impedance. For TM waves the influence of the metal films on the GHS is comparatively weak. The experiments are carried out with microwaves. Keywords: Goos-Haenchen shift; nano-metallic films, microwaves PACS: 42.25.Bs, 42.25.Gy, 42.50.-p, 73.40.Gk
