Some inventions are so mind-blowing, they sound like science fiction,but they’re real, and they’re changing the world. In ...

A possibility is presented to realize left-handed planar substrates for microstrip applications. For this purpose the known split ring resonator based structure is adapted to a multilayer PCB process.

We designed and fabricated a kind of NbN-gold hybrid metamaterial-based modulator. They had tunable spectra response under thermal stimuli. This terahertz (THz) wave active modulator possesses good ...
