Thanks so much! Exactly the type of answer I wanted. The math comments very helpful.
So I guess Smits used numerical methods in 1958? Do you all assign HW problems that require numerical methods?
The grinding the boundary idea is neat, thanks. I would think the non-negligible thickness...
Is my question too hard or too easy? Help, IANAP. I don't even want to know an answer, I just want to know how hard a question is and how/where it would fit into classical E&M? Undergrad? Grad? Neglected topic? [I hope not the last, since this is actually a practical result and not just a...
See ref (Smits, 1958, Bell Technical Journal: http://onlinelibrary.wiley.com/doi/10.1002/j.1538-7305.1958.tb03883.x/abstract (also Google will show a pdf copy that is not pay-walled)
The paper describes correction factors for doing 4 probe conductivity measurements on cylinders (semiconductor...
