Optimization of Ebg Structures by Use of Global Optimization Algorithms

چکیده
Planar dielectric EBG structures are formed by two-dimensional periodic dielectric inclusions in the dielectric slab. The main design parameters forming the frequencies of stopband are the shape of inclusions and their size, kind of slab it is formed in, lattice constant and both slab and inclusions permittivity constant. While there does not exist a general way how to determine the stopband existence of certain parameter setup analytically it must be simulated by use of numerical methods.
