Simulation of Symmetrical and Asymmetrically Shielded Helical Lines
Properties of the unshielded symmetrical and asymmetrically shielded asymmetrical helical systems are considered in the paper. Models of systems based on the multi-conductor method and the CST Microwave Studio software package are used. The expressions for the retardation factor and the input impedance of the systems are derived using the multi-conductor line method. Analysis of the retardation factor allowed us to show that there are possibilities to design the simple helical symmetrical systems or asymmetrical systems having good dispersion properties and relatively high characteristic impedance. Simulation made using the package CST Microwave Studio confirmed the properties of the systems discovered using the multi-conductor line method.
