The results show that the waveguide propagates electromagnetic waves independently from the sign of the dielectric permittivity of the filling material. The latter parameter and the geometry of the ...

Abstract: In this letter, a novel multichannel-coupled open resonator for terahertz (THz) wider frequency range measurement is proposed. The coupling of the THz open resonator is carried out through ...

The device they created is based on strontium titanate and potassium tantalate, two materials that display quantum paraelectric properties and a large field-tunable permittivity at low temperatures.

Liquid-liquid phase separation (LLPS) involving intrinsically disordered protein regions (IDRs) is a major physical mechanism for biological membraneless compartmentalization. The multifaceted ...
