Problems solved by technology
However, some magnetic metamaterials with specific functions applied in lower frequency bands (several megahertz to tens of megahertz) require materials with higher dielectric constant, lower dielectric loss, lighter texture and larger capacitance to act as substrates. , FR-4 grade copper clad laminates obviously cannot meet the above requirements

Abstract
The invention provides a metamaterial and a preparation method thereof. A baseplate of the metamaterial is a buried capacitance baseplate. The preparation method of the metamaterial comprises the following steps: 101, carving a plurality of artificial microstructures on a buried capacitance material which comprises a first side and a second side that are opposite to each other, fixing a first artificial microstructure layer consisting of a plurality of artificial microstructures on the first side of the buried capacitance material and fixing a second artificial microstructure layer consisting of a plurality of artificial microstructures on the second side; and 102, fixing the first and second artificial microstructure layers with prepregs respectively to obtain the metamaterial. According to the invention, the buried capacitance material is taken as the baseplate, so that the resonance frequency is effectively lowered, the baseplate of the metamaterial is thinner and lighter, higher in dielectric constant, lower in dielectric loss and larger in capacitance, the overall performance of the metamaterial is greatly enhanced, and a favorable development and application prospect is achieved.
Description
technical field [0001] The invention relates to the field of metamaterials, in particular to a method for preparing a metamaterial and the metamaterial. Background technique [0002] At present, there have been a lot of research on magnetic permeability in the international community, among which the research on positive magnetic permeability has become mature, and the research on negative magnetic permeability metamaterials is now a hot research topic at home and abroad. Negative magnetic permeability has Quantum polarization can polarize incident waves, so it has a wide range of effects, such as magnetic resonance imaging in the field of medical imaging. Negative magnetic permeability materials can enhance the imaging effect of electromagnetic waves. In addition, negative magnetic permeability materials It also plays an important role in lens research. In the field of engineering, magnetic permeability usually refers to relative magnetic permeability, which is the absolute...
