EZ-PowerPlane ©
Fast and Acurate calculation of the impdenace and S-parameters for Printed Circuit Board power-Ground/reference plane pairs.

Based on the closed-form cavity resonance formulas, EZ-PowerPlane allows users to create complex power plane shapes by combining rectangles and triangles. The effect of decoupling capacitor location, value, and ESR/ESL can be included in the impedance (or S-parameter) calculation.
