Psychotronic warfare

Extremely low frequency magnetic and electric fields of 6.67 Hz, 6.26 Hz and lower can be used to modify behaviour in humans and animals producing symptoms of confusion, anxiety, depression, tension, fear, mild nausea, headaches, and hemispheric EEG desynchronization. The established physics of radio propagation suggest that vast geographical areas can be readily mood-manipulated by transmission of such energy within the earth-ionosphere waveguide.

There are documented reports of efforts to test transmissions with these effects.
