From whence the Fresnel Zone constant of proportionality?
Good info, thank you! I'm starting to suspect that where F appears in the denominator it actually started its life as c/F to make the units under the root all be distance. I'm trying to work through getting sqrt(c) and the distance units conversion factor out from under the root to see if...- joe80211

From whence the Fresnel Zone constant of proportionality?
Calculation of the Fresnel Zone given as r=M*sqrt( 1/F * (d1d2/(d1+d2))) uses 72.1 and 17.3 as the constant of proportionality (M) for r in feet and meters respectively. Does anyone know where this constant comes from? I've tried plugging-and-chugging with feet-to-miles, and f=c/lambda, but I...- joe80211
