本发明涉及一种人工电磁材料， 特别是涉及一种人造微结构及其应用的人 工电磁材料。 背景技术 The present invention relates to an artificial electromagnetic material, and more particularly to an artificial microstructure and an artificial electromagnetic material for use thereof. Background technique
磁导率是表征磁介质磁性的物理量， 常用符号 μ表示， μ等于磁介质中磁感 应强度 Β与磁场强度 Η之比， 一般的基板上面附着一块金属薄片的结构得到的 磁导率不能满足我们的要求。 Permeability is a physical quantity that characterizes the magnetic properties of a magnetic medium. It is usually expressed by the symbol μ. μ is equal to the ratio of the magnetic induction intensity Β to the magnetic field strength 磁 in a magnetic medium. The magnetic permeability obtained by attaching a piece of metal foil on a substrate cannot satisfy our Claim.
人工电磁材料 ( metamaterial )是一种具有天然材料所不具备的超常物理性 质的人工复合结构材料， 通过对微结构的有序排列， 改变了空间中每点的相对 介电常数和磁导率。 人工电磁材料可以在一定范围内实现普通材料无法具备的 介电常数和磁导率， 从而可以有效控制电磁波的传播特性。 The artificial metamaterial is an artificial composite structural material with extraordinary physical properties not possessed by natural materials. By orderly arranging the microstructures, the relative dielectric constant and magnetic permeability of each point in the space are changed. The artificial electromagnetic material can realize the dielectric constant and magnetic permeability which are not available in ordinary materials within a certain range, thereby effectively controlling the propagation characteristics of electromagnetic waves.

The superposition of these two materials produces an equivalent dielectric constant and permeability in the space, which correspond to the electric field response and magnetic field response of the material as a whole. The electromagnetic response of an artificial electromagnetic material is characterized by the characteristics of the artificial structure, and the electromagnetic response of the artificial microstructure is largely determined by the topographical features and dimensions of the pattern of the metal wire. The size of the artificial microstructure depends on the frequency of the electromagnetic wave that the artificial electromagnetic material is responsive to, typically one tenth or less than one tenth of the wavelength of the electromagnetic wave to be responsive, otherwise the arrangement of artificial microstructures in space cannot be considered continuous.

负磁导率效果并不明显， 且此时根据图 3 的虚线可知人工电磁材料对电磁波的 损耗很大， 并不适合应用。 发明内容 At present, the artificial electromagnetic material production process usually adopts the artificial microstructure of the open "concave" ring as shown in Fig. 1, and the artificial electromagnetic material including the open "concave" ring artificial microstructure is shown in Fig. 2, and the manual shown in Fig. 2 The magnetic permeability of the electromagnetic material changes with frequency as shown in Fig. 3. When the normal operating frequency is 5.2 GHz, the magnetic permeability is about -5. Since the absolute value of the magnetic permeability is small, it can be used. The negative magnetic permeability effect is not obvious, and at this time, according to the broken line of Fig. 3, the artificial electromagnetic material has a large loss of electromagnetic waves, which is not suitable for application.
