Simulation on the Electromagnetic Environment in the Carrier of Airborne VLF Wire Antennas

The airborne VLF (Very low frequency) transmitting system is commonly used in underwater communication with a very high power, which produces a complement electromagnetic field. It may threaten to the equipment and personnel on the aircraft. In this paper, the electromagnetic environment inside the aircraft with airborne DTWA (Dual Trailing Wire Antenna) is studied based on the numerical simulation software FEKO. The aircraft model and the VLF transmitting system model are established. By calculating the radiation near field of the DTWA, the electromagnetic field distribution and the induced current of the cables inside the aircraft cabin are analyzed. The conclusions are helpful for the further research on the application of airborne VLF communication system.
