Abstract

A new measurement method of the magnetoimpedance at high frequency is hereby proposed. The method is based on the S-parameter measurement of a specific cell consisting of a section of magnetic sample in the form of wire or ribbon suspended on a ground plane. Some experimental results are reported to show the effectiveness of the technique.
