Abstract

The invention relates to a terahertz dual-band metamaterial based on electric resonance. The metamaterial comprises a substrate and a metal layer unit, wherein the metal layer unit is provided with an electromagnetic resonance unit which comprises two split resonant rings and a closed ring; the closed ring is positioned between the two split resonant rings; and the metal layer unit is paved on the substrate in a periodic array manner. The terahertz double-band metamaterial is simple in structure and low in manufacturing cost, has the advantages of strong resonance, wide band and dual frequency points, can be effectively applied to terahertz function devices with various requirements on wide band design.

Description

technical field [0001] The invention relates to functional devices of terahertz solid-state electronics, in particular to a terahertz dual-band metamaterial based on electric resonance. Background technique [0002] Since the discovery of electromagnetic waves, human beings have been trying various efforts, hoping to control electromagnetic waves at will and make them serve human beings. Since the 19th century, the development of radar, radio, sensor network, etc. has greatly accelerated the speed of human society, and at the same time, it has made human beings' requirements for electromagnetic wave control devices more and more intense. The most direct way to control electromagnetic waves is to add different materials to its propagation path to change its propagation properties, but traditional materials in nature are increasingly difficult to meet the demand for electromagnetic wave control. Especially in the terahertz band, traditional materials exhibit very weak electro...
