Description
[technical field]
The present invention relates to electromagnetic arts, in particular, relate to a kind of Novel manual electromagnetic material.
[background technology]
Artificial electromagnetic material, is commonly called as Meta Materials, is a kind of novel artificial synthetic material, be the substrate be made up of nonmetallic materials and attachment on the surface of the substrate or the multiple man-made microstructure being embedded in substrate inside form.Substrate can be divided into multiple square substrate unit of rectangular array arrangement virtually, each base board unit be attached with a man-made microstructure thus form a metamaterial unit, namely whole Meta Materials is made up of, just as crystal is made up of according to certain arrangement countless lattices hundreds thousand of, 1,000,000 even more than one hundred million such metamaterial unit.Man-made microstructure in each metamaterial unit is identical or incomplete same.Man-made microstructure is the certain geometric cylindrical or flat wire of composition, such as, form the wire etc. of annular, I shape.
Due to the existence of man-made microstructure, each metamaterial unit has the effective dielectric constant and equivalent permeability that are different from substrate itself, and the Meta Materials that therefore all metamaterial unit are formed presents special response characteristic to Electric and magnetic fields; Meanwhile, different concrete structures and shape are designed to man-made microstructure, effective dielectric constant and the equivalent permeability of its unit can be changed, and then change the response characteristic of whole Meta Materials.
Dielectric constant is take insulating material as medium and be the ratio that medium makes the capacitance of same sized capacitor with vacuum, and usually use Greek alphabet ε to represent, it represents in unit electric field, the size of the electrostatic energy of savings in unit volume.Dielectric constant characterizes dielectric polarization and stores the ability of electric charge.If there is the material of high-k to put in the electric field, the intensity of electric field can have considerable decline in dielectric.In high dielectric constant material, electromagnetic wavelength is very short, greatly can reduce the size of radio frequency and microwave device.The excursion of the most dielectric constant of existing material is all very little, and is generally the dielectric constant being greater than zero.
Usually I shape man-made microstructure is adopted to go the dielectric constant distribution changed in space in existing artificial electromagnetic material design production technology.The dielectric constant distribution that this structure produces usually only produces once association and shakes in the frequency band paid close attention to, thus change in dielectric constant scope is smaller, and be usually all change from a larger value, but the dielectric constant of the change that usually needs in practical application to start from scratch.
[summary of the invention]
The object of the embodiment of the present invention is to provide a kind of Novel manual electromagnetic material, and this material has wideband high-k and in another frequency range, has the dielectric constant distribution increased gradually by zero in certain frequency range.The embodiment of the present invention is achieved in that a kind of Novel manual electromagnetic material, and described material comprises:
Plate shape substrates, is attached to the man-made microstructure on described plate shape substrates, and described man-made microstructure has at least one pair of, and the often pair of man-made microstructure comprises attachment the first man-made microstructure on the substrate and the second man-made microstructure.
The embodiment of the present invention obtains two resonance peaks by two different man-made microstructure, make can to realize ε between described two resonance peaks to start from scratch smooth gradual change, and from analogous diagram relatively, change the size of man-made microstructure resonance peak can be made to move forward in certain frequency range or after move, and then regulate ε to start from scratch the frequency range of smooth gradual change, concrete Changing Pattern is: the size reducing micro-structural, and band bandwidth described in ε can be made to broaden, and resonance peak moves after the meeting; Increase the size of micro-structural, band bandwidth described in ε can be made to broaden, and resonance peak can move forward, and described artificial electromagnetic material has wideband high-k before first resonance peak, can meet the demand of specific occasion.
