Metal-particles of the submicrometer size range are embedded in conventional dielectric materials. The resulting electromagnetic behavior of such a heterostructured dielectric shows novel properties which are of fundamental importance both for basic research and technical applications. Here we report on the prensently available dielectric parameters. Depending on the metal partical size its volume filling factor and the preparation procedure, the complex dielectric function can be taylored for the respective demands: dieelectric loss, frequency dependends, temerature dependends as well as additional mechanical and thermal properties can be adjusted in a range having never been achievable before.
