Trapping T-rays for better security scanners
Date:7/11/2013

Medical diagnostic and security scanners with higher sensitivity could result from University of Adelaide research into detecting T-rays (terahertz waves).

Published in the journal Advanced Optical Materials, the researchers describe a novel structure which traps terahertz waves in tiny (micro-scale) holes to produce much higher contrast imaging than currently possible.

Terahertz waves, which are electromagnetic waves with frequencies between those used for mobile phone communications and for optical fibre communications, are used for some airport body scanners and other security scanners to see through packages and clothes. They are also capable of distinguishing malignant from healthy tissues for cancer detection.

"This work takes an unconventional path to detecting terahertz waves," says Dr Withawat Withayachumnankul, project leader and ARC Postdoctoral Fellow in the University's School of Electrical and Electronic Engineering.

Dr Withayachumnankul has worked with RMIT University in Melbourne and Albert Ludwigs University of Freiburg in Germany to produce the new structure using metamaterials (materials that show non-natural properties with the use of carefully engineered structures).

The structure is made of tiny (micro-scale) cavities etched into the surface of silicon. Terahertz waves that hit the structure are captured and compressed inside the cavities.

"By tailoring the silicon properties through the use of micro-structures (the size of a cross-section of human hair) it is possible to trap and confine the waves in a volume much smaller than the wavelength of the terahertz waves," says Dr Withayachumnankul.

"This significantly improves the efficiency of terahertz devices such as scanners and will have broad impact on biomedicine and homeland security, where better contrast means more accurate identification."

RMIT team leader Dr Sharath Sriram says: "We needed to carefully
