Researchers Create Terahertz-Permeable Aerogel Material

The terahertz range includes the high frequency wavelengths that lie between microwaves and infrared light on the electromagnetic spectrum. Because terahertz waves can pass through most non-conductive materials non-destructively, the frequency range lends itself to multiple applications, making it a promising tool for future research. However, hurdles remain. For one, terahertz radiation is difficult to produce efficiently, and the materials necessary to receive and adjust transmission of the waves are largely unknown.
