Finite Element Method (FEM) based and analytical models are developed for both single wire Sommerfeld and Goubau lines. Starting with the Sommerfeld type wave, we derive the analytical expression based on the assumption that the two-wire surface wave is a superposition of the two surface waves on the individual wires. Models are validated via measurements and a comparison study conducted between the analytic and the FEM-based computations for coupled Sommerfeld type lines. We then investigate the coupling ","authors_text":"A. Al Rawi, D.Molnar, M.C.Payne, T.
