Abstract

We report on an experimental demonstration of two-way communication between sky and underwater for the first time. Signal transmission from sky to underwater is realized by the thermoacoustic effect (TE), while from underwater to sky, this is based on the microwave vibration measurement (MVM). With a homemade experimental setup, the two-way transmission of “UESTC” is realized. This study suggests that TE combined with MVM has the potential to be used for two-way wireless communication between sky and underwater.

Highlights

On the other hand, the wireless signal transmission from underwater to sky is based on detection of the displacement information in the water–air interface induced by modulated ultrasound signals.12 In this study, the underwater system sent the modulated ultrasound signal via a 3.5 MHz transducer (SU-102, Sonic concepts) placed at 10 cm underwater, where the signal comes from a function generator (33220A, Agilent)
