Abstract
In this paper, a Zero index metasurface (ZIM) loaded highly directive Yagi antenna is proposed for Microwave imaging of corrosion in steel-reinforced concrete (RC) structure. The zero index metasurface (ZIM) enhanced the gain of the reference Yagi antenna by $4\mathrm{~dB}$ at 9GHz. A numerical model of the cylindrical metallic targets with and without corrosion inside the RC structure is designed for electromagnetic (EM) analysis. The proposed ZIM-based Yagi antenna transmits $\mathbf{E M}$ signal and receives the scattered data from the RC structure, which is applied into a piecewise synthetic aperture radar (SAR) algorithm to enhance the spatial resolution of the target object. The numerical results show that the proposed microwave imaging technique using the ZIMbased Yagi antenna and SAR algorithm detects both the cylindrical shape metallic target with and without corrosion inside the RC structure and is also able to identify the corroded metallic target.
