Networks of high frequency inhomogeneous transmission lines

[摘要] It is well known from classical transmission line theory, that transmissionlines can be folded into impedances and thereby used in an electrical networksetting. But it is also possible to create large networks of transmissionlines consisting of tubes and junctions. The tubes contain the transmissionlines and the junctions consider the mutual influences of the adjacent tubesor the terminals. The calculation of the currents and voltages at thejunctions can be performed with the help the BLT-equation. So far this methodis not applicable for nonuniform transmission lines described in a full wavemethod, because the lack of a distinct voltage gives no possibility forjunctions. Junctions only make sense, when the considered network offers thepossibility to propagate a TEM-Mode. If this requirement is fullfilled,nonuniform transmission lines could be included in an electrical network.This approach is validated in this paper in form of numerical simulations aswell as measurements.
