Description
[technical field]
The present invention relates to Meta Materials field, particularly relate to the Meta Materials of a kind of ceramic composite and preparation thereof.
[background technology]
Meta Materials refers to that some have the artificial composite junction of the extraordinary physical property not available for natural material
Structure or composite.By the structurally ordered design on the key physical yardstick of material, can be broken through certain
The restriction of a little apparent natural laws, thus obtain the meta-materials merit of the common character intrinsic beyond nature
Energy.The character of Meta Materials and function mostly come from its internal structure rather than constitute their material, because of
This, for design and synthesis Meta Materials, people have carried out a lot of research work.2000, Duke University
Smith et al. point out that the composite construction of the metal wire of periodic arrangement and open loop resonator (SRR) can
To realize DIELECTRIC CONSTANT ε and magnetic permeability μ simultaneously for negative double negative material, also referred to as LHM.Afterwards he
Further through making metal wire and SRR composite construction achieves the double of two dimension printed circuit board (PCB) (PCB) is upper
Negative material.
Existing Meta Materials man-made microstructure is generally metal material, and medium substrate typically uses organic tree
Aliphatic radical plate, the dielectric constant of organic resin baseplate material is generally between 3～5, and for Meta Materials
For some application, generally require the high dielectric constant material of comparison as medium substrate, various meeting
While mechanical performance, it is difficult to search out suitable material.
If but using some high-ks, low-loss material, the product mechanical performance of preparation is not
Only good, fine and close, uniformly, it is also possible to be prepared as different shapes to meet industrial demand；
Medium ceramic material on the market includes Barium metatitanate. and some oxides, such as SrO, WO3、PbO、
B2O3Or rare earth etc., although the dielectric constant of substrate prepared by this medium ceramic material is higher, loss
Ratio is relatively low, but does not reaches the Meta Materials requirement to high-k (being greater than 35), has meanwhile
A little somewhat expensive such as rare earths of oxide, also some oxide is poisonous, is not suitable for large-scale use.
