FDC: clarification on skin depth

[Elliott Wolin <wolin@jlab.org>]

Hi,

The skin depth in copper is (6.6 cm)/sqrt(frequency) (from Physics Vade Mecum, AIP Press, 
eq. 1.07.C.13).

The skin depth decreases with frequency, leading to the well known "skin effect" in 
conductors.  Thus higher frequencies have a smaller skin depth, and penetrate less than 
lower frequencies.


				Sincerely,
					Elliott
