An Improved Differential CSRR-Based Sensor for Characterizing the Magneto-Dielectric Materials

This paper presents an improved complementary split-ring resonator (CSRR)-based sensor for differential measuring permittivity and permeability of magneto-dielectric materials. The sensor has two identical resonator elements, one of which is used as reference and the other is used to characterize magneto-dielectric materials. By combining these two resonator elements together, the sensor can fully characterize the magneto-dielectric materials with the environmental interference suppressed effectively.
