Abstract

Przedmiotem wynalazku jest sposób otrzymywania naturalnego materiału o ujemnym współczynniku załamania charakteryzujący się tym, że miesza się co najmniej dwa związki chemiczne w postaci sproszkowanej, z których we wspólnym zakresie częstotliwości przynajmniej jeden związek posiada ujemne wartości przenikalności dielektrycznej, a drugi ujemne wartości przenikalności magnetycznej, po czym mieszankę związków poddaje się prasowaniu wstępnemu, a następnie powstałą wypraskę poddaje się prasowaniu zasadniczemu, przy czym prasowanie przebiega w warunkach podwyższonego ciśnienia. Materiał uzyskany sposobem znajduje zastosowanie między innymi jako osłona elektromagnetyczna, antena, absorber, supersoczewka, czy filtr fal elektromagnetycznych.The subject of the invention is a method of obtaining a natural material with a negative refractive index, characterized in that at least two chemical compounds are mixed in powder form, of which at least one compound in the common frequency range has negative dielectric permeability values and the other negative magnetic permeability value after whereby the compound mixture is subjected to pre-compression, and then the resulting compact is subjected to primary compression, wherein compression is carried out under elevated pressure. The material obtained by the method is used, among others, as an electromagnetic shield, antenna, absorber, super-lens or electromagnetic wave filter.
