- Institute of Technology Madras and the University of Nairobi have used metamaterials to improve detection of defects in large structures by guided wave ultrasound.
- Metamaterials are artificially crafted materials with unique internal microstructures that give them properties not found in nature.
- Potential applications of metamaterials are diverse and include optical filters, medical devices, remote aerospace applications and among others.
- Guided wave testing (GWT)
- Sound waves are sent along the length of the structure rather than into the structure, allowing the waves to travel longer distances.
- GWT has poorer resolution than conventional ultrasound-based testing due to diffraction limitations.
