摘要： A microwave circular waveguide cavity and filter containing said cavity has a circular iris mounted transversely within the cavity. The iris has an eccentrically located circular aperture that is sized and located to control coupling between modes resonating in the cavity. The cavity can be a dual mode cavity, a triple mode cavity or a higher mode cavity. In a method of constructing such a cavity, coupling can be controlled by choosing from a number of variables including the size of the aperture, the offset distance, the inclination angle, the thickness and the location of the iris within the cavity.
