## Abstract The resonant cavity perturbation technique is usually used to measure the complex permittivity of various dielectric materials at microwave frequency. The values of real and imaginary part of the complex permittivity of the material under test can be deduced from the measured shift of r

✦ Synopsis
A ca¨ity 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 wa¨eguide ca¨ity. From the shift in the resonant frequency and the Q-¨alue, the complex permeability of the material can be e¨aluated.

## Abstract The design of a rectangular cavity resonator implies to solve the Maxwell equations inside that cavity, respecting the boundary conditions. The resonance frequencies appear as conditions in the solutions of those equations. When a small piece of a magnetic material is introduced in the
## Abstract In this article, we propose a new method to measure the complex relative permittivity (ε~r~ = ε − __j__ε) and permeability (μ~r~ = μ − __j__μ) of liquid‐ or powder‐type materials using a two‐port probe which is constructed from coaxial transmission lines. The two‐port probe is a simple
