[Ground-station] [50MHzandUp] COVID-19 Microwave Inactivation Research - Parts needed

[Dr. David Rogers]

Tony:

I have available for you:

2 ea WR-137-to-Nf transitions;

2 ea 46-in Semflex stainless steel armored cables; precision N male straight one end, precision N male right-angle opposite end; extremely low-loss (0.5 db) at 14-GHz; rated for 100w CW through 15-GHz; designed to take repeated flexing; and,

1 ea WR-112 (7-11-GHz) horn with WR-112-to-Nf transition (sorry but only one of each).  Picture of the horn antenna on request.

Give me an address, and I will ship.

Dave

> Fellow microwavers - it is time to apply your hobby to help save lives!  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.

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.

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.
