Abstract
Experimental results from a study investigating the inactivation of bioaerosols containing Bovine Coronavirus (BCov) under repetitively pulsed radio frequency (RF) electromagnetic exposure will be presented. These experiments were performed in a waveguide containing a flowing aerosol stream and were limited to the use of a single RF waveform: ~2 μs square envelope, 5.6 GHz, 4.8 kHz repetition rate. Aerosol streams were exposed to pulsed RF electric field amplitudes in the range of 41.9 +/- 6.2 kV/m. Compared to the results of the control (no-RF) experiments, RF waveform exposure results in a 74% reduction in mean survival rate of the aerosolized BCov. RF exposure was also demonstrated to have a substantial impact on the variance of the experimental results, with the RF exposure data showing an 800% increase over the control results. Experimental results will then be compared to those from an analytic electromagnetic-heating inactivation model for aerosolized pathogens.
