F. Tefiku et E. Yamashita, EFFICIENT METHOD FOR THE CAPACITANCE CALCULATION OF CIRCULARLY SYMMETRICAL VIA IN MULTILAYERED MEDIA, IEEE microwave and guided wave letters, 5(9), 1995, pp. 305-307
The equivalent capacitance produced by a circularly symmetric via conn
ecting two microstrip lines on different planes is efficiently calcula
ted by using the rectangular boundary division method. The calculation
is carried out considering effects of inhomogeneous media within the
line structures as well as the ground conductor thickness on the capac
itance produced by a microstrip via. Computational results for various
via geometries are presented and compared with presently available da
ta.
