Absorption of Electromagnetic Waves into Periodic Structure and Thin Film of Metal when a Resonance of Plasmons Appears as a Result of Prism Excitation
ABSTRAKT
Using the coupled wave method an absorption of electromagnetic waves in a grating-metallic substrate system has been analyzed; in so doing a grating can be both dielectric and metallic. It is proved that at certain wavelength resonance of plasmons can be achieved, that results in completed absorption of electromagnetic wave by system. For comparison the research of plasmons resonance excited by a prism into thin silver film has been carried out. It is ascertained that here on certain conditions total absorption can be attained, too, at that within resonance range a strong dependence on incidence angle at metallic film has been observed. It is shown that for both methods of plasmons excitation within resonance range the identical dependences of reflectance on refractive index of medium, which contacts directly with gratings and thin metallic film, has been observed, at that the refractive index change by 0.001 leads to the reflection coefficient change from zero to 0.8.
