A method is presented for calculating the capacitances and inductances
per unit angle of circularly curved multiconductor transmission lines
in multilayer printed boards. The capacitances and inductances of the
90 degrees sector of the axially symmetrical structure are used for m
odeling a multipin connector analyzed with SPICE. By introducing the K
ronecker product, the method becomes simple in programming, even for a
great number of layers. The present paper is a first step to combinin
g the 2D-FD (finite-difference) method and the MOL (method of lines).
