Primitive cell scattered type electro-magnetic forbidden band structure

Abstract

The invention discloses an electromagnetic forbidden zone structure with an original cell discrete 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 spiral photon crystal; a cycle original cell of the plane spiral photon crystal is intertwined by a helix; the helixes of the neighboring original cell are mutually isolated; the helix comprises more than one spiral wire and each spiral wire is intertwined symmetrically; the original cells of the plane 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 bandgap material applied in the electromagnetic field, in particular to a discrete electromagnetic bandgap structure. 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 structures include the ...
