Kai Li During the past decades, Prof. Kai Li has published 34 international journal papers on the studies of ELFSLFVLFLF electromagnetic waves propagation. In the past three years, he and his research group at Zhejiang University has achieved a great progress on the SLFELF wave propagation and applications theoretically.
WADI ELECTROMAGNETIC VLF
WADI utilizes the magnetic components of the electromagnetic field generated by long-distance radio transmitters in the VLF Very Low Frequency band. Conductive structures on the surface or underground, even when covered with thick overburden, affect locally the direction and strength of the field generated by the transmitted radio signal.
ELF and VLF Electromagnetic Field Effects Persinger
Extremely low frequency ELF electromagnetic fields can occur as waves between about I Hz to 100 Hz or as short pulses within this range of very low frequency VLF and higher frequency sources. The natural occurrence of ELF signals is associated with weather changes, solar disturbances and geophysical ionospheric perturbations.
