Abstract
The optical properties of a light filter consisting of a transparent dielectric matrix with inclusion of metallic nanoparticles of various shapes and sizes are investigated theoretically. By selecting distributions of nanoparticles, it is possible to achieve absorption of electromagnetic radiation in specified spectral regions of visible or near IR radiation. Such filters have narrow transition regions, high contrast and low fabrication temperature in comparison with well known absorption filters. A filter for absorption of optical radiation transparent in the infrared region and an infrared filter transmitting optical radiation are considered as examples.
