Investigation of Slow-Wave Structures Using Synergy of Various Methods

Software packages based on numerical methods allow modeling structures that are close to real systems and finding their final characteristics. This chapter presents results of simulation of some special types of slow-wave systems and proposes the idea of application of synergy of various methods to investigation and design of wide-band slow-wave structures. Inhomogeneities of meander systems can be symmetrical or asymmetrical with respect to the longitudinal axis of the meander system. Only symmetrical inhomogeneities are usually taken into account in models of meander systems. The periodical asymmetrical inhomogeneities are modeled by capacitances connected to one side of the meander electrode. The model used, based on multiconductor lines, does not take into account that bending of the lateral parts of the meander electrode in the H-profile meander system causes a change of the period of the meander electrode. The multiconductor line method allows to model infinitely long slow-wave systems.
