Scientists control super fast frequencies by using high temperature superconductors

Imagine an imaging technology that could see deep into human tissue without the harmful side effects of radiation. Super-fast oscillations of radio waves, called terahertz (THz) have that promise, but so far, controlling them has been beyond reach.
But now, by using layered high temperature superconductors, researchers at the University of Michigan and RIKEN, Japan have proposed a way to cherry pick these ultra-fast waves, letting only certain waves pass through, similar to how we tune a radio.
