Abstract

A method is proposed to create materials with a desired refraction coefficient, possibly negative one. The method consists of embedding into a given material small particles. Given $n_{0} (x)$ , the refraction coefficient of the original material in a bounded domain $D \subset R^{3}$ , and a desired refraction coefficient $n (x)$ , one calculates the number $N (x)$ of small particles, to be embedded in $D$ around a point $x \in D$ per unit volume of $D$ , in order that the resulting new material has refraction coefficient $n (x)$ .
