Phononic crystals are composite materials made of periodic distributions of inclusions
embedded in a matrix. Due to their periodic structure, these materials may exhibit under …

It is known that the transmission spectrum of the so-called locally resonant phononic crystal
can exhibit absolute sharp dips in the sonic frequency range due to the resonance scattering …

The propagation of acoustic waves in a phononic crystal slab consisting of piezoelectric
inclusions placed periodically in an isotropic host material is analyzed. Numerical examples …

The acoustic properties of three-and two-dimensional phononic crystals consisting of hollow
