Applications of Split Ring Resonator (SRR) antennas for the evaluation NDT of GRP pipelines [2022-2024]
Our project purpose to produce SRR (Split Ring Resonator) antennas for Non-destructive testing (NDT) by microwave technical. The challenge is to use these devices to control pipelines of Glass Fiber Reinforced Plastic (GRP). This work aims to design and develop a sensor system and to experimentally demonstrate the feasibility of this system for the detection of sub-wavelength defects in GRP composites. The SRR antenna is a device widely used in microwave techniques. Generally, they are used in several applications such as: Microwave filters, oscillators, tuned amplifiers, food quality control, biomedical sensor, NDT evaluation and characterization of materials (Composite, Concrete, Wood, etc.), chemical and compositional analysis of materials. The SRR (microwave) antenna will be realized by two experimental methods. The first method is the Printed Circuit Board (PCB), the second method is the photolithography. The dielectrics of the SRR antennas produced by photolithography will be elaborated by materials of ABO3 type. A comparison between the results obtained by the two methods is necessary to confirm the reliability of photolithography in our research project. The design of the SRR antennas will be realized using several techniques, namely the PCB printing technical, Magnetron sputtering and elaboration techniques (solid-state synthesis). Characterization techniques will be implemented to characterize the prepared dielectric pellets, namely the XRD, the SEM, the AFM and dielectric characterizations. Measurements by a vector network analyzer VNA is necessary to determine the Scattering parameters S and the resonance frequencies of the devices produced. Simulation studies will be effectuated by HFSS software to optimize the realization parameters of SRR antennas and the results of the evaluation of GRP pipelines.
