“…At any point r in the xy-plane, the potential V is due to s T on all interfaces. From Reference [13], after eliminating the term corresponding to the image charge, since there is no infinite planar ground plane for the cylindrical structures considered here, the potential at any point in the xy-plane is expressed as…”

SUMMARYIn this paper, a numerical technique suitable for characterizing a wide variety of interconnection configurations printed on cylindrical surfaces, is presented. The interconnection lines may have either finite or infinitesimal cross-sections. To model cylindrical interfaces, suitable space-domain integral equations are formulated to represent the potential on conductors and electric field at dielectric interfaces. The solution of the integral equations is then obtained numerically by applying the method of moments (MOM). The objective of this approach is to determine the capacitance matrix of cylindrical interconnection systems with different configurations. From the capacitance matrix, other quantities such as characteristic impedance, coupling coefficient and effective permittivity can be determined. The numerical technique described in this paper is implemented as a general computer program. Various circular cylindrical as well as elliptical cylindrical structures have been solved including microstrip lines and coplanar waveguide lines. The results obtained compare very well with other published data.
