Özet

A promising microwave non-resonant method has been proposed for accurate constitutive parameter measurement of magnetic materials. The method eliminates the undesired ripples in the extracted parameters by using a medium-loss reference sample and employing one reflection and one transmission measurements. In addition, it is non-iterative and based on point-by-point (frequency-by-frequency) extraction, which is useful for fast constitutive parameter measurement of dispersive materials. It is validated by measurements of a low-loss sample at X-band.
