Description

RF magnetic properties of conductive plane magnetic sheets are analyzed to provide a basis for applications of magnetic alloy tapes to RF accelerating cavities. This paper reports on the effects of eddy current on the magnetic properties of the sheets when the frequency of the applied magnetic field increases up to RF frequencies. A nonuniform magnetic field distribution, formed within the sheet by eddy currents, is obtained by solving a field equation based on Maxwell's equations, which include conductivity and complex permeability. The resulting distribution is used to derive expressions for RF magnetic properties of the sheet, such as effective permeability, magnetic power loss, and Q-value. (author)
