Aerogel could become the key to future terahertz technologies

Posted by in categories: biotech/medical, security

High-frequency terahertz waves have great potential for a number of applications including next-generation medical imaging and communication. Researchers at Linköping University, Sweden, have shown, in a study published in the journal Advanced Science, that the transmission of terahertz light through an aerogel made of cellulose and a conducting polymer can be tuned. This is an important step to unlock more applications for terahertz waves.

The covers wavelengths that lie between microwaves and infrared light on the . It has a very high frequency. Thanks to this, many researchers believe that the terahertz range has great potential for use in , security technology and communication systems, among other things.

In , it can also be an interesting substitute for X-ray examinations as the waves can pass through most non-conductive materials without damaging any tissue.
