Wide-Band Slow-Wave Systems

2.6  Principles of Modeling of Slow-Wave Structures

Modeling of electrodynamic slow-wave systems using the multiconductor line method consists of several steps:

1.  The multiconductor line with the cross-section shape and dimension that are the same as in the MCL is used in the model.

2.  The segment of the MCL of length (in x direction) corresponding to the length of conductors in the real system is considered (Figure 2.6).

3.  Boundary conditions are applied. In the general case, loads with impedances ${\underset{\_}{Z}}_{n+i}^{+}\text{and}{\underset{\_}{Z}}_{n+i}^{-}$ are applied to conductors of the segment; here, i is the number of the period and n is the number of conductors in the period.

4.  Equations describing relationships between voltages and currents at the ends of conductors are ...
