Analysis of Corrugated Coaxial Line with the Use of Body of Revolution and Finite Element Method
A combination of the body of revolution and finite element methods is utilized to the analysis of coaxial lines with corrugated rod and wall. Both periodic and non periodic structures can be investigated. As the structure is axially symmetrical the two dimensional scalar vector finite element method can be used, which allows for the investigation of complex geometries and is computationally efficient. A generalized impedance matrix at the line ports is calculated from which the scattering parameters are derived. A few examples of corrugated coaxial lines have been analyzed and the results were compared to those obtained from commercial software.
