Calculation of Characteristic Impedances of Multiconductor Lines

In the application of the multiconductor line method for investigation of slow-wave systems, we must have values of characteristic impedances of multiconductor lines used in the models of the systems. Formerly, methods based on conform transformations were used for calculations of characteristic impedances. Unfortunately, errors in values of characteristic impedances are followed by errors in calculations of characteristics of slow-wave structures.

We can reduce errors of calculations using numerical methods (finite difference, finite element, integral equation) [1,2,3,4,5,6,7,8,9,10,11]. Taking this into account, in this chapter, we present brief information about fundamentals ...
