PLASMA MODEL-ONE MODEL OF ELECTROMAGNETIC RESPONSE OF MATTER

The prerequisite and mode of electromagnetic response of nano metal/dielectric films to electromagnetic wave field were suggested. With the carrier density and the reflectance, transmittance of the film, the plasma frequency and the dependence of absorptance on the frequency of electromagnetic wave field were calculated respectively. The calculated results accorded with the experimental ones, which proved the plasma resonance is one mode of electromagnetic response.
