A cavity perturbation technique suitable for measuring magnetic parameters of ferrite materials is discussed. Rod‐shaped samples or a ferrite‐powder‐filled capillary tube are placed at the position of maximum magnetic field in a rectangular waveguide cavity. From the shift in the resonant frequency and the Q ‐value, the complex permeability of the material can be evaluated. © 1998 John Wiley & Sons, Inc. Microwave Opt Technol Lett 18: 241–243, 1998.
