A simple approach is suggested and implemented in a set of computational experiments to solve the problem of the synthesis of 2-D photonic crystals of finite thickness with ultra-wide bandgaps for the plane incident waves. The results are given for the case of normal incidence of E -polarized wave; similar structures can be easily synthesized in the case of an arbitrary polarization of the field and under additional requirements concerning the interval of angles of arrival of an obliquely incident wave. In crystal synthesis, the rather natural for this electromagnetic problem bottom-up approach has been used.
