Thermoacoustic Effect Turns Microwaves into Underwater Sound

In the thermoacoustic effect, heat from electromagnetic waves striking the water’s surface generates sound waves. A University of Arizona team has demonstrated benchtop thermoacoustic communications (TAC), successfully transforming microwave signals in air into sound signals under water, received by an acoustic sensor. The experiments and theoretical analysis suggest a new approach to air-to-underwater communications.
