摘要
It is proposed to create materials with a desired refraction coefficient in a bounded domain D subset of R-3 by embedding many small balls with constant refraction coefficients in to a given material. The number of small balls per unit volume around every point x is an element of D, i.e., their density distribution, is calculated, as well as the constant refraction coefficients in these balls. Embedding into D small balls with these refraction coefficients according to the calculated density distribution creates in D a material with a desired refraction coefficient.
