“…T he accurate detection of material permeability and permittivity is crucial in a variety of disciplines, including biomedical [1], manufacturing, industrial [2], and military [3] fields. Different methods can be used according to the application environment and the type of sample under test (SUT), such as transmission line method [4], free space method [5], waveguide method [6], and near-field method [7]. Within the microwave frequency range, methods for characterizing materials can be simply classified into resonant method and non-resonant method.…”

A dualport microstrip sensor based on a complementary split ring resonator (CSRR)-derived structure is proposed to measure the permittivity and permeability simultaneously in this paper. The coupling among meandered conductive ring, interdigital capacitor, and microstrip line is used to obtain the relatively independent distribution area of the highest intensity of the electric field and magnetic field. It can be utilized to distinguish the influence of permittivity and permeability on the resonant frequency point. A numerical model was established for extracting the magnetic and dielectric properties, and the sensor was processed and tested. The findings demonstrate that the sensor can measure permittivity and permeability in a single operation by taking advantage of the resonant properties of low and high frequencies. The relative errors of the measured permittivity and permeability are controlled within 4.43% and 3.41%, as well as the sensitivity values S f m and S f e of 7.24 and 3.06, indicating excellent overall performance.
