Kmecl P., Jerman I., Škarja M. (2000): Microwave electromagnetic field affects the corona discharge pattern of water. Electro and Magnetobiology 19(2): 135-148
Abstract:
We investigated the influence of microwave irradiation (cw; 10 GHz)
on water by means of corona discharge electrography. Water drops from previously
irradiated and control water were exposed to a high-voltage, high-frequency
electric field on a photographic plate. Electrographs of the corona discharge
around control and irradiated drops were taken simultaneously, and the
images obtained were analysed by computer. Several parameters relating
to the luminosity, shape, and streamers of the image were calculated and
tested nonparametrically. The results show a distinct, nonlinear behavior
of corona discharge patterns (both radially and angularly) in water drops
exposed to different microwave densities (5 x 10^-1 – 5 x 10^-8 mWcm-3).
