In this paper, we design a meta-material surface emulating a perfect magnetic conducting plane (PMC) using the hierarchical genetic algorithm (HGA). This is achieved by manipulating the unit-cell geometry of frequency-selective surface screens and the electrical properties of the supporting dielectric medium in the optimization process. The properties of the structure are evaluated using a method of moments (MoM)-based electromagnetic solver. By virtue of the HGA, prior information of the number of FSS screens and dielectric layers is not required. The designed PMC is employed as a dipole-antenna reflector for gain enhancement.
