In the quasi-static approximation the spectrum properties of the electroacoustic waves in a 4mm ferroelectric in the presence of the periodical domain structure were considered. It was shown that the electroacoustic waves significantly modify the wave spectrum caused by the motion of the domain boundaries.

The theory of elastic waves propagation in phononic crystal is developed. Two mathematic methods are considered, namely, the multipole propagation method and Bloch–Floquet method. Dispersion dependencies and band structure for both models are calculated and analyzed. Mathematical approach for modeling of a real phononic crystal is proposed.

The necessary conditions for high-effective multi-beam Bragg acoustooptic diffraction (i.e. laser beam splitting into several beams of predetermined powers) are found. The effect is observed in case of the input electric signal being a combination of several mono-chromatic components with equidistant frequencies and determined amplitudes and mutual phases. An optimizing algorithm for вшffraction efficiency maximization is developed. The high-effective splitting into 3–7 beams is experimentally realized.
