Embodiment Construction

[0026] The invention relates to an electromagnetic wave converging element, which can make two beams of incident electromagnetic waves converge into one electromagnetic wave when leaving the element, thereby increasing the energy density of the electromagnetic wave and facilitating the electromagnetic wave to propagate farther.

[0027] Such as figure 1 As shown, the electromagnetic wave concentrating element of the present invention is composed of one or more metamaterial sheets with the same thickness, and these metamaterial sheets are arranged and assembled at equal intervals, or the front and rear surfaces of two sheets are directly bonded Stacked into one structure.

[0028] Each metamaterial sheet includes a substrate 1 whose front and rear surfaces are parallel to form a sheet of equal thickness, and also includes a plurality of artificial microstructures 2 attached to the front surface of the substrate 1 or embedded in the middle of the substrate 1 .

[0029] These ar...

Abstract

The invention relates to an electromagnetic wave converging element which comprises at least one metamaterial sheet layer, wherein each sheet layer comprises a sheet-shaped nonmetal substrate, each substrate is divided into a plurality of completely-same and array-distributed cuboid substrate units, an artificial micro structure is attached on each substrate unit, the artificial micro structures on each line of substrate units have same index ellipsoids which are mutually in parallel; and the artificial micro structures on each line of substrate units have same index ellipsoids, optical axes of extraordinary light axis of the index ellipsoids are sequentially clockwise or counterclockwise rotate, and the rotation angle of the optical axis of the last extraordinary light axis in the line of substrate units relative to the optical axis of the first extraordinary light axis does not exceed 180 DEG, so that the extraordinary light axis of each line of the index ellipsoids is positioned on the same side of a normal of a center connecting line of each line of substrate units. By adopting the invention, electromagnetic wave convergence can be realized.

Description

technical field [0001] The invention relates to the field of electromagnetic communication, in particular to an electromagnetic wave converging element made of metamaterials. Background technique [0002] Metamaterial is a new type of material, which is composed of a substrate made of non-metallic materials and multiple artificial microstructures attached to the surface of the substrate or embedded in the interior of the substrate. Artificial microstructures are cylindrical or flat metal wires that form a certain geometric figure, such as ring-shaped, I-shaped metal wires, etc. Each artificial microstructure and its attached or occupied part of the substrate constitute a unit, and the entire metamaterial is composed of hundreds of thousands, millions or even hundreds of millions of such units, just like a crystal is composed of countless lattices according to Each crystal lattice is equivalent to the above-mentioned artificial microstructure and a unit composed of a part of...
