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 ${\underset{\_}{Z}}_{n+i}^{+}\text{\hspace{0.17em}}\text{and}\text{\hspace{0.17em}}{\underset{\_}{Z}}_{n+i}^{-}$ 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 ...
