Enabling High Bandwidth Wireless Communication through Seawater and Conductive Enclosures Igor Smolyaninov (443) 474-1676 firstname.lastname@example.org What are we trying to do? Click here. What are we trying to do? Broad-band RF communications between underwater unmanned assets over distances RF 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 revolution Our patented antennas are optimized for excitation of partially longitudinal waves (such as plasmons, etc.) in combination with patent-pending novel impedance matching techniques Plasmons do “impossible” things!

What is new about our approach? surface wave-assisted communication through seawater Numerical simulations of surface wave excitation by underwater antenna Surface wave propagation length: Surface wave penetration depth: at 20 MHz If operation at -90 dB is assumed, corresponding depth is d ~l0 /3 ~ 5m at 20 MHz The communication distance L and depth d will increase with larger free space wavelength l0 Want to see the results?

Field testing and projected performance - Submersible (up to 30 min/up to 1 m deep) Yaesu FM Transceiver VX-8 operated - When antennas are submerged knee deep (~0.5 m) signal can be detected up to about Testing Results: at 50 MHz with the custom underwater antennas produced by Saltenna LLC. 10 meters, which is much larger than the 4 cm skin depth at 50 MHz. first generation underwater antenna Meet the team, Click here.
