For analysis of wide-band slow-wave systems, the electrodynamic and multiconductor line methods have been most frequently applied [1,2]. The main shortcoming of these methods is related to waste of time resources for modeling and derivation of analytical expressions of the dispersion equation and input impedance. Moreover, infinite length systems are mostly simulated by the electrodynamic and multiconductor line methods; therefore, effects related to limited lengths of real systems cannot be evaluated. For these reasons, we tried to apply versatile electromagnetic simulation and design tools developed for investigation of electromagnetic fields and simulation of various electrodynamic systems.
