The specific measurement pertains to detecting VLF/ELF radiation from the ionospheric dynamo current system that has been periodically modified by pulsing the HF high power transmitter at VLF or ELF. Because of the nonlinear relationship between ionospheric conductivities and electron temperature, the ...
To understand the generation mechanism of ELF/ VLF hiss, incoherent Cerenkov radiated power [2] from the low latitude and middle latitude plasmasphere are evaluated. From the plot of the total computed power (spectral density) as a function of frequency for various L-values, we observed that ...
EMF/ULF: electromagnetic field source from typical residential electrical power Household electrical current, home wiring, electric meters, service entry cables. Power Transmission lines Note that power transmission lines and home 120V or 240V appliances operating on 60 cycle alternating current are working...
A network devoted to a continuous monitoring of LF, VLF transmitters and ELF signals was set up in Central Italy, and has been operating since 2006, which is currently composed of 9 stations in 9 different Italian cities. From the beginning of 2012, improvements have been carried out on the...
Electromechanical Transmitters for ELF/VLF Radio Jarred S. Glickstein & Soumyajit Mandal Part of the book series: Synthesis Lectures on Engineering, Science, and Technology ((SLEST)) 110 Accesses Abstract Receiver sensitivity was a significant limitation of the prototype ELF communication channel ...
ELF/VLF wave generation via ionospheric HF heating: Experimental comparison of amplitude modulation, beam painting, and geometric modulation [1] Generation of ELF/VLF radio waves (300 Hz to 10 kHz) is achievable via modulation of natural currents in the lower ionosphere with high-power HF (2&nd...
