This paper presents a one-port reflective-mode phase-variation microwave sensor consisting of a coplanar waveguide (CPW) transmission line terminated with a grounded open complementary split ring resonator (OCSRR). The sensor is useful for measuring

A microwave device able to detect differential-mode to common-mode conversion (or vice versa) in a four-port balanced circuit is proposed. For mode conversion detection, the balanced circuit should be fed by a differential-mode signal, generated by m

Defect detectors and comparators, able to detect tiny differences between a reference (REF) sample and a material under test (MUT), are presented in this paper. In one version, the comparator is implemented by means of a rat-race hybrid coupler and a
