What are we trying to do?Broad-band RF communications between underwater unmanned assets over distancesRF communication through (partially) metal enclosures (warehouses, shipping containers)What is new about our approach? Click here. What is new about our approach?Saltenna takes advantage of the plasmonics/metamaterial revolutionOur patented antennas are optimized for excitation of partially longitudinal waves (such as plasmons, etc.)in combination with patent-pending novel impedance matching techniquesPlasmons do “impossible” things!What more is new about our approach?

What is new about our approach?surface wave-assisted communication through seawaterNumerical simulations of surfacewave excitation by underwater antennaSurface wave propagation length:Surface wave penetration depth:at 20 MHzIf operation at -90 dB is assumed, correspondingdepth is d ~l0 /3 ~ 5m at 20 MHzThe communication distance L and depth d will increase with larger free space wavelength l0Want to see the results?
