The nearfield analysis of T VLF antennas

Taking the T antennas set on the level ground in the valley as examples, method ofMoment (MOM) is used to solve the Pocklington integral equation. The nearfield intensity distribution is analyzed and the field intensity at different spots with different distances from the transmitting antenna is calculated .The result provides important basis for surrounding electromagnetic environment assessment of the high power very low frequency(VLF) antenna.
