For this reason, metamaterials have been studied in the microwave spectral range, where index-near-zero 1 and epsilon-near-zero (ENZ) behaviours have been predicted theoretically 2,3,4 and ...
GPS-based navigation, communication systems, electrical power grids and financial networks all rely on the precise time kept by a network of around 500 atomic clocks located around the world.
Masers, which are like lasers that operate in the microwave spectral range, can reliably keep time but have limited accuracy. "The stability of the masers ...
