Abstract

The invention discloses a reflective microwave segment programmable 1-bit metasurface for multi-beam forming, comprising an upper resonant ring, an upper dielectric layer, a middle bottom plate, a lower dielectric layer and a bottom layer sequentially arranged from top to bottom Microstrip line; the upper resonant ring is used as a passive resonant unit structure; the bottom microstrip line is used for phase shifting; the metasurface is arranged according to digital 0 and digital 1 for programmable shaping of multiple beams. The invention performs resonance through the resonant ring, and the structure is centrally symmetric to ensure angular stability; the bottom plate is placed in the middle of two layers of medium, and the problem that the reflection efficiency of the existing reflective metasurface is not high is solved.

Description

technical field [0001] The invention belongs to the technical field of electromagnetic field and microwave communication, and in particular relates to a reflective microwave section programmable 1-bit metasurface for multi-beam forming. Background technique [0002] In recent years, the proposal and development of artificial electromagnetic surface (Metasurface, also known as metasurface) provides a new method and means for electromagnetic wave regulation in the millimeter wave and microwave frequency bands. An artificial electromagnetic surface is an artificial electromagnetic structure with unique electromagnetic properties, which is usually composed of periodic arrangement of subwavelength units. Through unique arrangements and designs, properties not found in natural materials can be achieved. By designing the structure and size of the metasurface unit, it can be ensured that the metasurface can work in a specific working frequency band, and can precisely control the el...
