Research Description: The transfer of information between identical chaotic elements is of great interest in understanding the dynamics of large coupled networks. To explore the synchronization characterizations of such a network, I have begun examining methods for radio frequency signal transmission between chaotic oscillators. Coupling through radio transmission, rather than hard-wire connections, will allow for through-wall transmission as well as additional elements to be more easily added into the network.
Due to the chaotic nature of the signal, the frequency spectrum of the chaos falls under the category of FCC regulation 47CFR15.503 for Ultra Wideband (UWB) signals. I have been researching antennas and modulation methods that will enable bi-directional coupling between identical elements, as well as keep our transmission within legal limits. This transfer of information will be used to couple two or more of these elements in an area for further study. With small affordable devices operating within FCC regulations, the dynamics of a many bodied chaotic network can be studied in real time to evaluate current theories and explore applications in commercial technologies.
