Analysis of Nonhomogeneous Helical Systems Using Electrodynamical Methods

Models of helical systems are composed using surfaces with isotropical and anisotropical conductivity and magnetodielectric layers among them [1,2,3]. As a result of the solution of Maxwell’s equations, a dispersion equation can be derived. Using this equation, we can find the retardation factor and characteristic impedance versus frequency.

The electrodynamical method has been successfully applied for analysis of homogeneous helical systems by Vainoris, Kirvaitis, and Staras [1], Staras et al. [2], and Kirvaitis [3]. In this chapter, we will consider application of an electrodynamical method for analysis of nonhomogeneous systems. The chapter is based on Staras, Skudutis, ...
