Abstract

The invention discloses a broadband polarizer based on the metamaterial; the polarizer ischaracterized in that a first dielectric plate, a second dielectric plate, a third dielectric plate, a fourth dielectric plate and a copper grounding plate are sequentially arranged, a first opening resonance circular ring is arranged between the first dielectric plate and the second dielectric plate, a second opening resonance circular ring is arranged between the second dielectric plate and the third dielectric plate, and a third opening resonance circular ring is arranged between the third dielectric plate and the fourth dielectric plate. The first opening resonance circular ring, the second opening resonance circular ring and the third opening resonance circular ring are arranged in a concentric circle mode, the broadband polarizer based on the metamaterial achieves a multi-layer resonance ring superposition structure with the overall height of 12.8 mm, and the polarization conversion characteristic of over 99% within the frequency band of 2.7 GHz to 4.6 GHz is also realized.

Description

technical field [0001] The invention relates to the technical field of polarizers, in particular to a broadband polarizer based on metamaterials. Background technique [0002] A metamaterial generally refers to an artificial periodic structure that possesses physical properties not found in natural materials. In recent years, metamaterials have attracted widespread attention from scholars for their exotic electromagnetic properties. At the same time, metamaterials also have important application prospects in controlling the polarization state of electromagnetic waves. Polarization converter is a device with the function of controlling the polarization direction of electromagnetic waves, and it is a very important device in the application of electromagnetic wave propagation, especially in the fields of nanophotonic devices and advanced sensors. In addition, in the microwave band, polarization converters also play a vital role in the design of circularly polarized antennas ...
