[Abstract]:As a new type of material, artificial electromagnetic material (metamaterial) has been paid more and more attention by researchers since the end of the 20th century. These characteristics mainly include inverse Cherenkov effect, inverse Doppler effect and inverse Snell refraction phenomenon. Moreover, these strange characteristics make people have great expectations for the future development of artificial electromagnetic materials. There is a limited frequency band in the radio wave, which is microwave. The frequency is between 300MHz and 300GHz, and the wavelength is between 1mm and 1m. Microwave is a kind of electromagnetic wave, so the wave-particle duality is one of its characteristics. The properties of microwave generally show the phenomenon of absorption, reflection and penetration. The vessels through which microwaves can travel are porcelain, plastic and glass. The material that can reflect microwave is usually metal. 3D printing is the core technology of the "third Industrial Revolution" and a kind of rapid prototyping technology. Textile fabrics are widely used because of their economy, diversity and easy bending. Based on the advantages of 3D printing technology and textile fabrics, the artificial electromagnetic materials based on 3D printing framework and textile fabric matrix are studied in this paper. The main contents of this paper are: (1) the research progress of artificial electromagnetic materials at home and abroad is described, and the principle and application of artificial electromagnetic materials are expounded. (2) the design and preparation of artificial electromagnetic materials are discussed in detail. 3) based on 3D printing technology, the design and preparation of artificial electromagnetic materials are discussed in detail. A kind of artificial electromagnetic material structure of "hollowed-out cube" is designed and fabricated, which can realize transmission enhancement and strong electromagnetic resonance in different wave bands, and a three-dimensional microwave asymmetric transmission supermaterial structure is designed. The characteristics of electromagnetic transmission in the microwave band are studied. The results show that the electromagnetic wave can be rotated "left-right" when it is transmitted in the material. Based on the principle of textile fabric and absorbing wave, a kind of supermaterial absorber is designed. The structure is at 7.63 GHz. The absorptivity of electromagnetic wave is 98.70 and its structure is optimized.
