Approximations to Wire Grid Elastance

Warne, Larry K.; Langston, William L.; Campione, Salvatore

By using a multipole-conformal mapping expansion for the wire charges we examine the accuracy of approximations for the transfer elastance (elastance is the inverse of capacitance) of a one dimensional array of wires (wire grid). A simple uniform fit is constructed by introduction of the decay factor from bipolar coordinates into existing formulas for this elastance.
