Impedance matching element based on mixed material process

Abstract

The invention embodiment relates to an impedance matching element based on a mixed material process. The impedance matching element is arranged between a first medium and a second medium and comprises a plurality of functional flake layers. Each functional flake layer comprises a flaky substrate and holes arranged on the substrate. The substrate is divided into a plurality of table cells, and each table cell is provided with holes. The impedance of each functional flake layer of the element is continuously changed in a stacking direction of the functional flake layer. The impedances of the first functional flake layer and the last functional flake layer are respectively the same as those of the first medium and the second medium. The substrate of the impedance matching element based on the mixed material process provided by the invention is provided with a plurality of holes, and an electromagnetic parameter distribution of the substrate is adjusted by controlling the size and the distribution of the holes. An impedance gradient layer is formed by stacking a plurality of substrates. The impedance matching element is arranged between the two media for eliminating the impedance mutation of a medium interface, so as to solve the problem of electromagnetic wave energy loss caused by reflex when an electromagnetic wave passes through the interface of the two media.

Description

technical field [0001] The invention relates to the field of electromagnetic communication, in particular to an impedance matching element based on a mixed material technology. Background technique [0002] With the continuous development of science and technology, electromagnetic wave technology has gradually penetrated into all aspects of our lives. An important characteristic of electromagnetic waves is that they can propagate in any medium or vacuum. During the propagation of electromagnetic waves from the transmitting end to the receiving end, the loss of energy directly affects the distance traveled by the electromagnetic signal and the quality of the transmitted signal. [0003] When the electromagnetic wave passes through the same medium, there is basically no energy loss; and when the electromagnetic wave passes through the interface of different media, partial reflection will occur. Usually, the greater the difference between the electromagnetic parameters (diele...

Problems solved by technology

However, the current research on impedance matching in the process of electromagnetic wave transmission is still limited to circuits, and there is no relatively mature technology for impedance matching in space propagation.
