Abstract

This paper presents a systematic measurement of the noise suppression effect at GHz range, of many kinds of materials, mainly Co-based NGSM films, in order to find the distinguished noise suppressing materials and reveal the origin. In this report, we describe the roll of sheet resistance and magnetic loss on a near field noise suppression effect of thin films attached on a microwave transmission line in near field.
