Abstract
The wireless shipboard data coupler allows transmission of data through steel ship bulkheads and submarine pressure hulls without the need for special wiring penetrations. Shipboard sensing data with a 1.0 MHz current is injected into the steel plating adjacent to a ships bulkhead, or onto the pressure hull at any penetration providing an electrical path or discontinuity to the opposing side of the bulkhead or pressure hull through the use of copper-plated, threaded electrodes. The injected current flows as a surface, or 'skin effect' current between the electrodes and in an indirect, spread, pattern wrapping around the edge of the penetration. This produces a pattern of surface currents on the opposite side of the ships bulkhead or submarine pressure hull. As the injected current is modulated, the data is received on the other side of the bulkhead or pressure hull using coupling loops to sensing the electrical field generated by the surface currents.
