Abstract
The ionic-type phononic crystal (ITPC) is composed of two kinds of ferroelectric or piezoelectric media with a periodic superlattice structure. Through the piezoelectric effect, there is the coupling between the vibration of the superlattice and the electromagnetic (EM) wave that is similar to the coupling between the lattice vibration and the EM wave in ionic crystal. The ITPC thus exhibits interesting long wavelength optical properties, such as microwave absorption, dielectric abnormality and polariton excitation that exist originally in a crystal.
