Abstract

The invention discloses an unequal-wideband-gap plasma photonic crystal. The photonic crystal comprises multiple medium layers and multiple plasma layers, and is characterized in that the medium and the plasma are arranged in a staggered manner, the plasma is packaged by the medium at both sides of the plasma, the thickness of the medium of the photonic crystal in an electromagnetic wave incidence portion is different that the thickness of the medium of the photonic crystal in an electromagnetic wave transmission portion, and the thickness of the plasma of the photonic crystal in the electromagnetic wave incidence portion is different from the thickness of the plasma of the photonic crystal in the electromagnetic wave transmission portion. According to the unequal-wideband-gap plasma photonic crystal, an unequal-wideband-gap photonic crystal with a multiple frequencies can be obtained through adjusting the thickness of the medium and the thickness of the plasma in the electromagnetic wave incidence portion and the electromagnetic wave transmission portion.

Description

technical field [0001] The invention relates to the field of plasma, in particular to a plasma photonic crystal with unequal wide band gap. Background technique [0002] Photonic crystals, also known as photonic bandgap materials, are artificial microstructures that are periodically arranged by materials with different electromagnetic parameters. The periodicity can generate a photonic crystal bandgap, so that electromagnetic waves falling into the bandgap cannot propagate. Based on the above characteristics, photonic crystals are widely used in many fields. Plasma photonic crystals are a new type of tunable photonic crystals formed by the periodic distribution of the density of the plasma itself, or the interlaced periodic arrangement with other dielectric materials. Plasma is in the form of gas and has no fixed shape. Therefore, periodically arranged media are often used to form closed plasma. Plasma has a strong dispersion characteristic, and it has the properties of a ...
