Novel Selected Modes on the Conductor - Backed Slotline [PDF]

open access: yes, 2002
This paper presents a detailed full-wave analysis of the conductor-backed slotline. The occurrence of an even dominant mode is revealed. This mode may propagate alone from dc up to the frequency at which the first leaky mode sets up.
