Microwave and Dielectric Measurement Techniques

A microwave method based on complementary split-ring resonators (CSRRs) is proposed for dielectric characterization of planar materials. The technique presents advantages such as high measurement sensitivity and eliminates the extensive sample preparation procedure needed in resonance-based methods. A sensor in the sh…

Transmission-reflection methods suffer from the increasing uncertainty in the phase of reflection scattering (S-) parameter measurements of low-loss materials. In addition, transmissionS-parameter measurements produce multiple solutions for the complex permittivity. In this paper, we propose a broadband and stable met…

A new sensor based on complementary split-ring resonators is presented to detect sub-millimeter surface cracks. The sensing mechanism is based on perturbing the electromagnetic field around an electrically small resonator, thus initiating a shift in the resonance frequency. The sensor is simple to fabricate and inexpe…

The effect of microwave output power and sample amount on effective moisture diffusivity were investigated using microwave drying technique on round okra (Hibiscus esculentus L.). The various microwave output powers ranging from 180 to 900 W were used for the determination of effective moisture diffusivity for constan…
