Design and optimization of heterogeneous multifunctional microstructures is of great interest to researchers in the field of material design. In this research, a new method for designing the microstructure of materials in order to achieve the desired properties using the surface approximation method based on multisided patch is presented. In multisided patch, based on boundary curves, the surface connected to these curves is approximated. For this purpose, first the boundary curves used to create the patch are determined and then the surface connecting these curves using the relation of multisided patch is presented. The resulting patch is then used to build a two-phase cell, which will alternately create the structure. Due to the flexibility of boundary curves, it is possible to construct various structures with different volume fractions. These structures are compared and evaluated based on the effective thermal conductivity. The results show that the proposed method is well able to provide structures with the desired ratio for thermal and electrical conductivity as well as diffusion coefficient for two-phase structures.
