Abstract

The invention discloses material with an electromagnetic forbidden zone structure of an original cell connected type, which comprises a parasitic element array, an earth plate, and a dielectric layer. The dielectric layer is arranged between the parasitic element array and the earth plate; the parasitic element array includes a plane photon crystal array; a plane photon crystal is a plane complementary spiral photon crystal; a cycle original cell of the plane complementary spiral photon crystal consists of a spiral-shaped gap which is periodically hollowed out by a substrate; and the spiral-shaped gap comprises at least one spiral gap or a plurality of spiral gaps. Each spiral gap is intertwined symmetrically and each spiral gap is mutually unconnected; and the original cells of the plane complementary spiral photon crystal present such shapes as a square, an equilateral triangle, a regular hexagon, etc. The pattern size of the cycle original cell provided by the invention is determined by an applied frequency scope. A linear relationship is formed when same substrate material is used and an accurate design can be made based on the current theory.

Description

Technical field: [0001] The invention relates to the field of materials, in particular to a band gap material applied in the electromagnetic field, in particular to a cell-connected electromagnetic band gap structure material. Background technique: [0002] Electromagnetic bandgap structures or photonic bandgap materials have broad application prospects in the field of microwave and optical communications due to their unique characteristics of suppressing the propagation of electromagnetic waves in a certain frequency band, and have aroused widespread interest in recent years. According to the different arrangements of periodic structures, they can be divided into four categories: three-dimensional, two-dimensional, one-dimensional and planar. Among them, the planar or quasi-planar structure has become the most researched aspect because of its low profile and simple preparation process. [0003] In the prior art, typical planar or quasi-planar electromagnetic bandgap struct...
