Abstract: A technique for calculating the electric field in interference coatings is described. The technique is used to find areas in the coating structure with electric field minima. Thin absorbing metal films are introduced into these areas during design. The results of calculating the transmission spectra of narrow-band interference filters with absorbing metal films are presented. It is shown that such metal-dielectric thin-film structures block radiation in the long-wavelength region of the spectrum.
Keywords: electromagnetic field amplitude, narrow-band interference filters, spectra, films, absorption, transmission.
