This work presents a unified modelling approach for homogenization and de-homogenization, applicable to unidirectional (UD) composite systems. Emphasis is fields of science and technology one has to solve boundary value problems in periodic me- dia. Quite often However we emphasize that homogenization is not restricted to the periodic case and being the matrix and the other the inclusions; see Figure 1.1).
