In Strong's text Hull claims the polarizability of a metal disc is (2/3)
the permitivity (space) times its diameter cubed. Finding this for a
sphere and even an infinite cylinder is trivial (once one has seen it
done). But a disc, no. Anyone know how it's done (not numerically)?
I've looked in many texts *, googled and not found it.
* not the best, unfortunately,
bc, wonders, will JD come to his rescue?

Page 2 shows a form factor consisting of the ratio
of disk thickness / disk diameter to find the polarizability of a disk
compared to that of the sphere. But this URL appeals to numerical
methods - specifically MATLAB .
Brian Whatcott Altus OK Eureka!
