Dispersion and attenuation of surface plasmon polariton at metal–dielectric interface

Bich Ha Nguyen and Van Hop Nguyen

Abstract

In the present work the behavior of a monochromatic electromagnetic wave propagating along the interface between dielectric and metallic media was rigorously studied. The exact analytical expressions of the electric and magnetic fields were derived. On the basis of the experimental data of the frequency dependent optical parameters of the media the dispersion and the attenuation of the surface plasmon polariton were determined by means of the numerical calculations
