Abstract
Magnetic and electrical properties of materials are investigated by the use of a novel method inspired by the known distance-to-fault (DTF) measurement. The principles of the one-port method are detailed and it is verified by presenting measurement results. The complex relative permeability and permittivity of the samples are derived simultaneously by means of a network analyzer and control software. The coaxial sample holder designed for this measurement allows the investigation of liquid and porous materials. As a special feature, the method can be easily implemented into various applications, since it is based on using a scalar network analyzer. Precognition of the sample length is not necessary, which provides high level of flexibility when using the presented method.
