Established a multiple scattering theory for spin-waves spectra in magnonic crystals.
Explained distinguishing features of the locally resonant and Bragg-type band gaps in magnonic crystals.
Developed a variation of a multipole expansion method for acoustic waves and applied the method to acoustic waves in microstructured optical fibers.
Formulated an effective medium theory for bulk and surface acoustic waves in microstructured metamaterials. Formulated conditions for a complex Doppler effect in acoustic metamaterials.
