SUMMARY
The objective of the proposed research is to design low power, miniaturized and ultrasensitive microwave transmission line based metamaterials, evaluate their performance then utilize them for bulk materials’ constitutive parameters extraction and other practical applications with a narrower scope such as nondestructive and microfluidic sensing. Also, the research aims to introduce, model and verify a condition of sensitivity uniformity for permittivity and permeability sensors. Planar metamaterial-based sensors feature high measurement accuracy, excellent imaging capability, design simplicity and flexible design parameters. Moreover, one of their significant advantages is their compatibility with the printed circuit board (PCB) technology which eases their integration with passive and active microwave components. These features allow the designer to easily customize the sensor design to realize various sensing platforms that are suitable for a wide range of applications. The research starts by revisiting the operational theory of CSRR based sensors to identify the influential factors that govern their performance. Then, the identified factors are going to be utilized to come up with sensing platforms with significantly improved and controlled sensitivity. As proof of concepts, the proposed platforms are going to be fabricated, tested and utilized for practical applications such as crack and microfluidic sensing.
