A DEVICE FOR DIRECT MICROWAVE MEASUREMENT OF PERMEABILITY AS A FUNCTION OF HIGH DC VOLTAGE

摘要

A sample holder and a coaxial method of measuring the permeability of magnetoelectric materials as a function of applied DC voltage are described. The sample holder reduces electromagnetic radiation losses as compared to conventional devices. The connections in the sample holder are electrically isolated from measuring equipment, preventing damage. A complementary algorithm to analyze the signal from the sample and calculate the permeability of the sample is described.
