Embodiment Construction

[0015] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0016] The embodiment of the present invention obtains two resonant peaks through two different artificial microstructures, so that ε can be smoothly and gradually changed from zero between the two resonant peaks, and it can be seen from the comparison of the simulation diagrams that changing the size of the artificial microstructure It can make the resonance peak move forward or backward within a certain frequency band, and then adjust the frequency band where ε smoothly and gradually changes from zero. The specific change law is: reducing the size of the microstructure can widen the bandwidth of t...

Abstract

The invention provides a novel manual electromagnetic material which comprises a piece-shaped substrate and at least one pair of artificial micro-structures. Each pair of artificial micro-structures comprises a first artificial micro-structure and a second artificial micro-structure which are adhered to the substrate, and a plurality of artificial micro-structures are arranged on the piece-shaped substrate in an array mode. Two harmonic peaks are obtained through two different artificial micro-structures, and smooth gradual change of epsilon from zero can be achieved between the two harmonic peaks. In addition, according to comparison of simulated images, we can know that the size of the artificial micro-structures can enable the harmonic peaks to move forward or backward in a certain frequency range, and then a smooth gradual-changing frequency range of a dielectric constant from zero is adjusted, wherein a change rule is specifically that the harmonic peaks move backward if size of the artificial micro-structures is decreased; and the harmonic peaks move forward if size of the artificial micro-structures is increased.

Description

【Technical field】 [0001] The invention relates to the electromagnetic field, and more specifically, relates to a novel artificial electromagnetic material. 【Background technique】 [0002] Artificial electromagnetic material, commonly known as metamaterial, is a new type of artificial synthetic 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. The substrate can be virtually divided into multiple square substrate units arranged in a rectangular array. Each substrate unit is attached with an artificial microstructure to form a metamaterial unit. The entire metamaterial is composed of hundreds of thousands, millions or even hundreds of millions of It is composed of such metamaterial units, just like a crystal is composed of countless lattices according to a certain arrangement. The artificial microstructures on each metamaterial ...
