Microwave Y-circulator device - has each port provided with two connections to ferromagnetic disc at specific angles to reduce unwanted nodes

摘要

The microwave Y-circulator has a ferromagnetic disc above or below the line junction and pre-magnetised at right angles to its plane. Each port is connected to the ferromagnetic disc at two places in order to suppress unwanted modes that cause sinusoidal electric field distributions of n times the transmitted signal period around the circumference of the ferromagnetic disc. These port connection points are distributed around the ferromagnetic disc at angles of k Pi/n where k = n and a whose number., If k is an odd number, the two connection points at each port are arranged so that their signals are in phase.
