Coupling to Wire Bundles in Rectangular Cavity

The motivation for this work was generated during the EMP testing of a ship. In order to collect data on the p o in ts o f in te r e s t , v o lta g e and c u rre n t probes were installed in hundreds of places in the ship and the data collected was transmitted to a recording station inside a shielded room, located somewhere in the ship. In order to communicate with this recording room, port­ able radios, in the VHF range were used. It surprised the authors that no matter where the transmitter was located, even several decks below the recording room, communication was established with no problem.
