Improved hybrid leapfrog ADI-FDTD method for simulating complex electromagnetic environment effects (E3) on a warship with multi-wire antennas

An improved hybrid leapfrog ADI-FDTD method is developed for accurately characterizing complex electromagnetic environment effects (E3) on a warship with multi-wire antennas in this paper. It has the capabilities for fast extracting mutual couplings (S-parameters) among different wire antennas as well as capturing induced current and electric field distributions on such an electrically large platform. All these information will be very important for controlling and suppressing (non) intentional electromagnetic interference (IEMI) on most high-speed data-link communication systems operating at UHF/VHF bands or even higher frequencies.
