I'm part of a small consortium working to determine whether the COVID-19 virus can be inactivated with RF energy. One of my colleagues published results a few years back with a different virus and it showed that the virus in question could be destroyed with a very reasonable field strength in the few Ghz range. Simulations show that the COVID-19 virus (which has a polarized, spherical shell) should resonate somewhere roughly in the 8-12 GHz range. We need to find the resonance(s) so we can build devices to destroy the virus.</div><div><br></div><div>Our test setup will involve two phases - first is spectral absorption measurement of a sample held between two horn antennas inside a bio-safety fume hood. We want to do this at very low power levels to avoid destroying the virus before it is characterized. Phase two will involve determining the energy density required to inactivate the virus.</div><div><br></div><div>We are starting first with a similar, but non-human coronavirus and if it shows promise we will move to the COVID-19 virus in a bio-hazard level 3 facility at either UC Irvine or Duke University. The academic team is working to get fast track funding now. </div><div><br></div><div>I would like to get a test setup going as soon as possible so that we can get this into the labs functional and with minimal intervention. To that end, this Friday, Rohde & Schwarz is dropping off a high performance VNA but I need some other loaner parts until we get budget to buy them. I imagine that among this community we can cobble together components and would love to have the amateur microwave community contribute to this important effort. I'll let you imagine how useful RF decontamination might be for a variety of scenarios.</div><div><br></div><div>Here's the team we've assembled:</div><div><font face="Times New Roman" color="#000000">
