"There are lots of practical advantages to this design, and we've already shown the best sensitivity to date in this 11-12 gigahertz frequency."

"These are electromagnetic rays in the range of around one hundred to several thousand gigahertz, comparable to the radiation of a cell phone or a microwave oven -- but with a significantly higher frequency."

THz waves are electromagnetic waves within the THz range, which falls between the microwave and infrared portions of the electromagnetic spectrum, typically spanning frequencies from 300 gigahertz to 3 THz.

Millimeter wave is the electromagnetic frequency between microwaves and infrared, ranging from 30 to 300 gigahertz.

That work involves looking for signals across a broad range of radio waves — including the gigahertz frequencies at which satellites communicate.
