Coupling capacitances in the planar conductive path system of the hybrid circuit with dielectric layer

This paper presents the analytical method of capacitance calculation for the hybrid circuit. The analyzed example of planar conductive paths, being a system of typical spatial configuration, is a part of research that is to develop a general, universal mathematic model to calculate parasite capacitances in hybrid structures. In general, this leads to solve the 3D boundary problem. The Fourier’s integral transformation has been used in order to determine the potential satisfying the Laplace equation.Resulting from here the equation system of electric charge distribution is being solved numerically by using the collocation method. On this basis the capacitance between conducting paths is calculated and experimentally verified.
