Enhancement of Microwave NDE Imaging using Metamaterial lens

This contribution focuses on the super resolution capability of metamaterial lens for nondestructive detection of sub wavelength defects in composite materials. Specifically, the lens is considered in conjunction with a microwave NDE system based on the Time Reversal method. Initial results demonstrate the capability of detecting and resolving subwavelength defects. The theoretical approach behind such a design, as well as preliminary simulation results, are presented to prove the feasibility of the method.
