"what would be interesting is a probe design that doesn't require 
penetrating the surface (e.g. I could put it on my concrete driveway)"

Jim, here is an interesting survey of the many ways to measure ground 
constants. I wish it had more detail on some of the more obscure 
methods. But the data section is fascinating. Where else are you going 
to find the HF dielectric constant of dry peridotite on the Kola Peninsula?
