Abstract

Two-dimensional quasi-photonic crystal as microwave focusing element is studied. The proposed structure is a random square-triangle tiling system with 12-fold symmetry and, hence, 12-fold symmetry quasi crystal. For this structure, finite difference time domain for illustration of focusing of the electromagnetic wave is used and results show that with suitable selection of crystal structure output signal is exactly the same as input one. The effective index of considered structure is near to -1. This situation is useful for small spatial dispersion that is necessary for focusing.
