Resonance-like Goss-Haenchen Shift induced by nano-metal films

摘要

The influence of nano-metal films on the Goos-Haenchen shift (GHS) isinvestigated. The films deposited at the total reflecting surface of a perspexprism/air have a sheet resistance varying between Z = 25 and 3 000 Ohm. Aresonance-like enhancement of the shift and of the absorption is found for TEpolarized waves, when the sheet resistance approaches the value of the vacuumimpedance. For TM waves the influence of the metal films on the GHS iscomparatively weak. The experiments are carried out with microwaves.
