Embodiment Construction

[0031] The specific implementation manners of the present invention will be described below in conjunction with the accompanying drawings.

[0032] Such as figure 1 As shown, the present invention provides a composite artificial electromagnetic structure suitable for receiving energy in any polarization direction, including 20 rows×20 columns of resonant units 1 regularly arranged along the orthogonal direction. Wherein, "arranging along the orthogonal direction" means that each row of resonant units is perpendicular to each column of resonant units.

[0033] In this embodiment, the number of resonant units can be adjusted according to needs, and it needs to be arranged in equal rows and equal columns in a periodic orthogonal arrangement.

[0034] Such as Figure 2-4 As shown, the resonance unit 1 includes a substrate 11 , four insulators 12 and four L-shaped pillars 13 .

[0035] The substrate 11 is square.

[0036] The material of the substrate 11 is copper. The ratio o...

Abstract

The invention discloses a composite artificial electromagnetic structure suitable for energy receiving in any polarization direction, and the structure comprises a plurality of resonant units which are arranged in equal rows and columns in the orthogonal direction. Each resonant unit comprises a substrate, four insulators and four L-shaped cylinders, wherein the insulators are fixedly embedded insubstrate through holes of the substrate, and are provided with jacks which are through holes, and the L-shaped cylinders are disposed on the substrate and each of the L-shaped cylinders has the two segments which are perpendicular to each other: one segment is perpendicular to the surface of the substrate, and the end part is fixedly inserted into the jacks; the other segment is parallel to the surface of the substrate. The L-shaped cylinders are corresponding to the insulators in a one-to-one manner, the four insulators are distributed at the top points of a square, the four L-shaped cylinders form the square through enclosing, and the adjacent L-shaped cylinders do not make contact with each other. The substrates of the resonant units are in seamless connection. The structure is advantageous in high efficiency, achieves any linear polarization and wireless transmission of energy.

Description

technical field [0001] The invention belongs to the field of electromagnetic technology, and relates to an electromagnetic structure, in particular to a composite artificial electromagnetic structure suitable for receiving energy in any polarization direction. Background technique [0002] Artificial electromagnetic structure is defined as an artificially manufactured uniform electromagnetic structure, which has abnormal characteristics that are not found in nature. It is an electromagnetic material structure composed of aperiodic or periodic arrangement of basic units of subwavelength artificial structures with specific geometric shapes. It has unique properties that the original materials in nature do not have, and many new physical phenomena appear in it. At present, the research on the physical characteristics of artificial electromagnetic structures and its application in the fields of directional radiation high-performance antennas, electromagnetic stealth, space commu...
