A novel method transforms common liquids into epsilon-near-zero materials using femtosecond laser pulses, enabling unique light manipulation at THz frequencies.

The phase and the group velocity of light propagating in conventional optical media cannot exceed the speed of light in vacuum. However, in so-called epsilon-near-zero (ENZ) materials, light exhibits ...

Electronic and spintronic devices are devices that use the properties of electrons to transmit, process and store information. Electronic devices use the electrical charge of an electron to encode ...
