Title of Paper:

Phonon-polariton and band structure of electro-magneto-acoustic SH wave propagation oblique to the periodic layered piezoelectric structures

Journal:

Physics Letters A

Summary:

Electro-magneto-acoustic SH waves propagating oblique to the periodic layered piezoelectric structures
are studied under the coupling of the acoustic wave and the electromagnetic wave. Band structures
of the so-called piezoelectric superlattice and phononic/photonic crystal are given both at acoustic
frequencies and at optical frequencies. For the periodic layered piezoelectric structures, phonon-polaritons
(the coupling modes of the phonons and photons) are found not only happening near the center of the
Brillouin zone (in the long-wavelength limit) at acoustic frequencies, but also being able to appear in the
whole Brillouin zone at optical frequencies. Appearing of these phonon-polaritons may provide a way to
design a new type of acousto-optic devices.
