A Portable Microwave Interferometry Sensor for Permittivity Detection Based on CCMRC [PDF]
IEEE Access, 2020 A portable microwave complex permittivity sensor based on the interferometry configuration is proposed. A complementary compact microstrip resonant cell (CCMRC) is applied as the sensitive element, which converts the dielectric information of the material under test (MUT) into the phase variations of its transmission coefficient.

A novel dual modality sensor with sensitivities to permittivity and conductivity
2017 IEEE International Instrumentation and Measurement Technology Conference (I2MTC), 2017 In this paper, an electromagnetic (EM) sensor which can operate simultaneously in capacitive and inductive modalities is developed, and a novel measurement strategy is proposed accordingly. The sensor is composed of two planar spiral coils with large track width, which promotes its capacitive mode.
