Abstract

The invention discloses an integrated design of a device with a three-dimensional all-medium non-resonant metamaterial structure and a manufacturing process. In the invention, the transform optics and the effective-medium theory are taken as the base, crisscrossed columns and diamond unit cells are used as a structure unit to be designed, and then the three-dimensional full-medium metamaterial structure with super broadband, low loss, easiness in three-dimensional expansion and the like is obtained; a photocuring rapid prototyping process is adopted for realizing the integrated design and themanufacture of the all-medium non-resonant three-dimensional metamaterial structure at a microwave frequency band (GHz); and a set of process method of integrated design and the manufacture of microscopic unit organizations and macroscopic three-dimensional structures for microwave invisible devices is set up.

Description

technical field [0001] The invention belongs to the technical field of microwave invisible metamaterials, relates to the preparation of microwave invisible metamaterials by using rapid prototyping manufacturing technology, and in particular relates to an integrated design and manufacturing process of a three-dimensional all-dielectric non-resonant metamaterial structure. Background technique [0002] In June 2006, J.B.Pendry and D.R.Smith published an article in the American magazine "Science", pointing out that by designing the structural characteristics of local units, metamaterials with specific spatial gradient distribution of electromagnetic wave refractive index ("positive" or "negative") can be obtained structure, so as to realize the control of the direction of electromagnetic wave propagation. In November of the same year, the D.R.Smith research team constructed a two-dimensional ring-shaped metamaterial structure by using a split resonator ring, and verified the fe...
