Abstract

The invention discloses an annular dipole resonance-based low-loss electromagnetic induction transparent metamaterial structure, and belongs to the technical field of a metamaterial. The annular dipole resonance-based low-loss electromagnetic induction transparent metamaterial structure comprises a rectangular dielectric substrate, an I-shaped metal line, a first resonator and a second resonator,wherein the I-shaped metal line is etched in the upper surface of the dielectric substrate, and the long edge of the I-shaped metal line is parallel to a symmetrical axis in the long edge direction ofthe dielectric substrate; the first resonator is etched in the upper surface of the dielectric substrate and positioned on one side of the long edge of the I-shaped metal line; the second resonator is etched in the upper surface of the dielectric substrate, and positioned on the other side of the long edge of the I-shaped metal line and symmetrical to the first radiator; and the first radiator and the second radiator both adopt spiral structures formed by rectangular structures through rotation of seven times, having the same width and different lengths. Based on electromagnetic field destructive effect interference between electric annular dipole resonance and electric dipole resonance, the radiation loss of the metamaterial is suppressed, and transmission coefficient is improved.

Description

technical field [0001] The invention belongs to the technical field of metamaterials, and in particular relates to a low-loss electromagnetic induction transparent metamaterial structure based on ring dipole resonance. Background technique [0002] Metamaterial is an artificial electromagnetic structure. Because its constituent elements can be designed arbitrarily, it has many abnormal electromagnetic properties, such as electromagnetic stealth, electromagnetic induction transparency effect, asymmetric transmission, polarization control, etc., and these properties use natural Material is unattainable. Although metamaterials have many important electromagnetic properties, their performance is limited by the occurrence of losses. In particular, when the losses are large, the performance of metamaterials and devices based on metamaterials deteriorates or even fails to work. [0003] The loss of metamaterials includes two parts: ohmic loss and radiation loss. Ohmic losses can...
