Reconfigurable Medium-matched Antenna for Structural Abnormality Detection (2025-2028)
Abstract
This project aims to improve the detection capabilities of microwave-based Non-Destructive Testing devices using a multi-element scanning setup. Each element will address existing challenges such as polarisation mismatch, scanning speed, surface reflection and penetration depth. In this system the phase front of the electromagnetic wave emitted by the antenna is shaped using a lens and the surface of the material being tested is given a specialised anti-reflection coating. This two-stage process ensures the emitted wave has sufficient directed power and is effectively transmitted inside the material to reach deep targets. Outcomes are expected to advance antenna system design and open new application areas for microwave technology.
