Anomalous light reflection at the surface of a corrugated thin metal film

The process of excitation of surface electromagnetic waves (SEW's) in corrugated thin metal film is investigated theoretically and experimentally. The existence of an anomalous increase of the reflection coefficient is demonstrated. The excitation of long-range plasmons in thin metal films open...

Description
Summary:The process of excitation of surface electromagnetic waves (SEW's) in corrugated thin metal film is investigated theoretically and experimentally. The existence of an anomalous increase of the reflection coefficient is demonstrated. The excitation of long-range plasmons in thin metal films opens new possibilities for sensor applications.
