description Microwave sensors for material characterization are the most widely used sensors in the food sector, quality control, biomedical, and industrial applications. One of the prospective methods for very precise dielectric material characterization measurements at a single or discrete frequency is the microwave resonant approach. Historically, waveguide, dielectric, and coaxial resonators have been used to characterize materials because they offer great sensitivity and precision. However, resonator sensors are typically large, expensive to produce, and require a large amount of material to detect the prior sample of the material being tested. Therefore, because of their benefits of being small in size, inexpensive, and simple to manufacture, planar resonant methods have become the most preferred approach in recent years. However, the poor sensitivity and low Q-factor value of this method limit the applicability for material characterization. Thus, this thesis introduces a single-band metamaterial to overcome the weakness of this technique by using the perturbation method in which the dielectric properties of the resonator affect the Q-factor and resonance frequency.
