Modulation of Rayleigh Waves

ISE has developed a method of frequency modulating seismic waves as a means of long-distance low-loss information transmission. The method exploits the physical fact that surface waves exhibit a significant amount of frequency dispersion over time allowing for a 'natural' form of modulation.

Imagine being able to transmit messages half-way across the globe using small amounts of energy and suffering negligible interference and signal losses. Better yet, imagine being able to transmit this information in a manner indiscernible from natural background noise. The potential applications of this should be obvious to anyone.

ISE is currently working on a prototype transmitter and receiver system as well as the necessary signal processing algorithms to advance the method from the blackboard to physical application.
