Abstract : The derivation of the overlap integral expressing the coupling coefficient between a pair of magnetostatic modes in a ferrite sphere is reviewed. The analysis is extended to the generalized ellipsoid with Gilbert damping terms incorporated in the general equations of motion for the magnetization. Experimental work in progress on the longitudinal pumping of a YIG disc under orthogonal detuning is discussed. (Author)
