While much attention has been given to ionizing electromagnetic stimuli which causes blatant and unalterable changes in biological systems, relatively little research has been concerned with those electromagnetic signals whose frequencies overlap with time-varying processes in living organisms. Extremely low...

ELF/ VLF hiss is a well-known form of electromagnetic emission having constant spectral density in the limited frequency band, which produces hissing sound [1]. Basically it is a whistler mode wave that interacts with energetic electrons in the magnetosphere. It is known that the result of thes...

Specifically, a 100kb/day was fixed to record the VLF power spectra intervals around the transmitter frequencies every 5 minutes. Similarly, a 600kb/day was fixed to record the ELF power spectra intervals, which was logarithmic spaced in frequency every 5 seconds. Furthermore, different physical...
