TE/TM (Transverse Magnetic/Transverse Electric) Height Profile Measurements of Transpolar VLF (Very Low Frequency) Signals
Transverse magnetic (TM) and transverse electric (TE) height-gain profiles of eight ground-based transmitters and one airborne transmitter were measured simultaneously by a rocket-borne wideband receiver flown at Thule AB, Greenland, under nighttime conditions. The profile shapes are shown to depend...
