This script calculates the impedance of the printed circuit board with two conducting traces positioned in the dielectric layer between two ground plates.
Conductors have rectangular cross-section with user defined width and height. Position of the first conductor is defined by the distance from the top grounded plate. Position of the second conductor is defined by X and Y spacing from the first conductor. The signal frequency and dielectric permittivity are user-defined as well.
Both electrostatic and magnetostatic analyses are performed for the PCB cross-section for self and mutual capacitances (C0, Cdiff) and inductances (L0, Ldiff) calculations. Corresponding FEA problems are automatically created and analyzed using QuickField API ActiveField
