Abstract

The invention relates to the technical field of dynamic continuously adjustable coaxial feed structures, and specifically discloses a coaxial feed structure with dynamically and continuously adjustable impedance based on graphene and two-dimensional semiconductors. The coaxial feed structure is composed of the two-dimensional conductors such as the graphene, molybdenum disulfide and like, and a single layer, a double layer or multiple layers of the two-dimensional semiconductors, and includes an intermediate dielectric structure layer. The coaxial feed structure further forms a diode and a field effect transistor, and is characterized in that functions of dynamically and continuously adjustable impedance RF impedance, impedance matching and impedance reconstruction of the coaxial structureare achieved by an applied electric field.

Description

technical field [0001] The present application relates to the technical field of a dynamically continuously adjustable coaxial feed structure, in particular to a dynamically continuously adjustable coaxial feed structure based on graphene and two-dimensional semiconductor impedance. Background technique [0002] Graphene is a single atomic layer metamaterial with many excellent electrical, thermal, mechanical and other material properties and broad application prospects, especially in the fields of electronics, communications and smart devices. Graphene is currently known as the material with the best electrical conductivity and has a unique energy band structure. Both theory and experiments have proved that the Fermi level of graphene can be increased or decreased by means of external electric field, doping, etc., and the conductivity of graphene materials can be effectively regulated. In particular, the unique performance of conductance tunability achieved by applied volt...
