Abstract

The invention discloses a scattering and wave-transmitting integrated electromagnetic coding metamaterial integrated with multiple phase regulation and control. The scattering and wave-transmitting integrated electromagnetic coding metamaterial is composed of metamaterial basic units of a multi-layer stacked structure. Each basic unit comprises a first metal layer, a first dielectric layer, a honeycomb layer, a second dielectric layer and a second metal layer which are arranged in sequence, wherein the first metal layer comprises a deformed Jerusalem cross, and the second metal layer comprisesa cross groove. Due to the special structural design, the units have anisotropism, and different reflection and transmission characteristics are shown under incidence of x and y polarized waves. According to the invention, the structure is simple, the processing is easy, the RCS reduction can be realized by using a scattering mechanism in a broadband, and a wave-transparent frequency point with high transmissivity exists in an RCS reduction band, so that the working environment of radio equipment is effectively improved.

Description

technical field [0001] The invention belongs to the field of new artificial electromagnetic materials, and more specifically relates to a kind of scattering and wave-transmitting integrated electromagnetic coding metamaterial integrated with various phase adjustments. Background technique [0002] New artificial electromagnetic materials, also known as electromagnetic metamaterials, are artificial materials composed of subwavelength structural periodic or quasi-periodic arrays. Electromagnetic metamaterials can control the amplitude, phase, polarization state, frequency and even angular momentum of electromagnetic waves, so they have attracted extensive attention. Metamaterials have a wide range of applications, such as absorbers, planar lenses, and polarization converters. [0003] In modern society, antenna technology has many applications, therefore, radome application has also received extensive attention. The radome can protect the antenna system from external interfe...
