Analysis of the Symmetric Y-Junction in Slotline

Millimetric circuitry in slotline uses Y-junctions, e.g. in diode mounts for mixers and power splitters. This work presents an effective approximate treatment of the problem, that exploits in full its symmetry (eigenvalues analysis) and utilizes partial wave analysis for an effective solution of the resulting boundary value problem, including radiation loss and junction parasitics.
