Proposed expansions for the capacitance of a square centered in a circle
Henry J. Riblet · IEEE Transactions on Microwave Theory and Techniques · 1994
Expansions for the capacitance per unit length of a square centered in a circle are proposed: one in terms of, /spl rho/, the ratio of the diameter of the square to the diameter of the circle and the other in terms of /spl delta/=1-/spl rho/. Limits on the accuracy of the expansion in terms of /spl rho/ are given in graphical form.>
