The paper discusses a system that enables high-power and high-data-rate transmission through solid metal barriers using ultrasound technology.
The system uses two piezoelectric transducers aligned on either side of a metal wall to create a channel, allowing for simultaneous power and data transmission without needing to penetrate the barrier.
It achieves impressive specifications, transmitting data at 17.37 Mbps and delivering 50 W of power through steel, while also suggesting future enhancements to increase performance for various military and industrial applications.
