摘要：

The influence of nano-metal films on the Goos-Hanchen shift (GHS) is investigated. The films were deposited at the total reflecting surface of a perspex prism and had a sheet resistance varying between Z(square) = 25 and 3 000 Omega. A resonance-like enhancement of the shift and of the absorption is found for TE polarized waves, when the sheet resistance approached the value of the vacuum impedance. For TM waves the influence. ence of the metal films on the GHS was marginali. The experiments were carried out with microwaves. (C) 2009 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
