Abstract
A new type of the geometry of the elements of hexagonal-lattice photonic crystal shaped as the Wigner-Seitz cell is proposed. Dispersion curves of electromagnetic waves are calculated and the photonic crystal band gap characteristics are determined using the plane wave expansion technique. It is shown that the proposed geometry of the photonic crystal element leads to band gap widening. A simple method for fabricating prototypes using negative electron lithography is proposed.
