Abstract

The invention provides a filtering radome. The filtering radome comprises a filtering assembly, and the filtering assembly comprises a dielectric layer and two structural bodies, of metamaterials, arranged opposite to each other in the external or internal surface of the dielectric layer. Each structural bodies of metamaterials comprises a substrate, first resonators and second resonators; the substrate includes a first surface and a second surface opposite to the first surface; the first resonators are arranged in the first surface in an array, and each first resonator comprises a first resonator microstructure; the second resonators are arranged in the second surface in an array, and each second resonator comprises a second resonator microstructure; and each second resonator is oppositeto one first resonator and coupled to the first resonator mutually. Thus, electromagnetic waves within the working frequency band can be transmitted in high efficiency, and electromagnetic waves beyond the working frequency band can be reflected in high frequency.

Description

technical field [0001] The invention relates to the technical field of radome, in particular to a filtering radome. Background technique [0002] A metamaterial is an artificial composite structure or composite material with extraordinary physical properties that natural materials do not have. Strictly speaking, a metamaterial is an artificial periodic structure whose unit scale is much smaller than the operating wavelength. Under long-wave conditions, it has an equivalent dielectric constant and an equivalent magnetic permeability. The electromagnetic parameters mainly depend on the properties of its basic constituent units. resonance characteristics. Therefore, by changing the geometric shape, size, and arrangement of the basic constituent units, the distribution of electromagnetic parameters in the metamaterial space can be changed, so that it can produce the expected electromagnetic response and flexibly control the propagation of electromagnetic waves. Due to its high...
