Dr. Lev S. SadovnikThe NewScientist article Microwave ray gun controls crowds with noise said
A US company claims it is ready to build a microwave ray gun able to beam sounds directly into people’s heads.
The device dubbed MEDUSA (Mob Excess Deterrent Using Silent Audio) exploits the microwave audio effect, in which short microwave pulses rapidly heat tissue, causing a shockwave inside the skull that can be detected by the ears. A series of pulses can be transmitted to produce recognizable sounds.
The device is aimed for military or crowd-control applications, but may have other uses.
Lev Sadovnik of the Sierra Nevada Corporation in the US is working on the system, having started work on a US navy research contract. The navy’s report states that the effect was shown to be effective.

Lev was the founder, president, and CEO of WaveBand until its acquisition by SNC. WaveBand is known for innovation in the field of millimeter wave imaging technologies, having developed a family of antennas whose beams can be reconfigured in real time without the use of expensive phase shifters. These antennas are now an integral component in many commercial and government systems, such as aircraft landing aids, missile seekers, and surveillance sensors.

Lev earned his M.S. degree in Physical Optics from the University of Chernovtsy (Ukraine) and his Ph.D. in Electrical Engineering from the University of Southern California (USC) and specialized in Optical Image Processing and Holography. He was a member of the Ukrainian National Field Hockey Team from 1976 to 1979.
