In this paper, a three-dimensional capacitance calculator is used for the accurate calculation of the per-unit-length (PUL) capacitance matrix of flaring, multiple, coupled microstrip, and stripline interconnections. Properly constructed Green's functions that satisfy the boundary conditions at dielectric interfaces are implemented in order to minimize the number of unknowns involved in the numerical solution. Under the assumption that the longitudinal components of the electric and magnetic fields are negligible compared to the transverse ones, the PUL inductance matrix is also found from the inverse of the capacitance matrix calculated for the same conductor geometry in a uniform dielectric medium.
