Selected Publications

Author or co-author have published over 30 research papers. Offered a new numerical method to

study thermoacoustic problems (ref.1). Given a proof of the equivalence between the energy velocity

and the group velocity for waves in piezoelectrics and under orther conditions (refs.4,5). Built a

traveling ring ultrasonic motor with the output torque of over 4 NM that is the largest torque for this type of motor.
