Device and method for producing novel plasma photonic crystal with five refractive indexes

Abstract

The invention relates to a device for producing novel plasma photonic crystal with five refractive indexes and a method for producing the novel plasma photonic crystal with five refractive indexes. The discharging condition is that the thickness of a discharging gap is 2.0mm, impressed voltage is 3.5-5.1kV, frequency is 55-60kHz, discharging gas is 99.1%-99.9%Ar, the remainder is air, air gap pressure is 0.6-0.8atm, temperature range is 285-320K, and humidity range is 70%-90%. According to the device and method, the conditions of the discharging gap, the impressed voltage amplitude and frequency, the content of argon and the like are changed, while the size of a water electrode is optimized, a temperature control adjusting device and a humidity control adjusting device are added, and four types of plasma channels formed by a plasma sheet, a thick plasma column and two types of plasma columns are obtained. The novel plasma photonic crystal structure with the five refractive indexes is formed by the plasma channels and a periodic arrangement self-organization in a non-discharging area. The novel plasma photonic crystal structure is more complex and has wider application prospects.

Description

technical field [0001] The invention relates to the field of plasma technology, in particular to a device and method for producing a novel plasma photonic crystal with five refractive indices. Background technique [0002] Plasma photonic crystals are a new type of tunable photonic crystals formed by the periodic distribution of the plasma's own density or the interlaced periodic arrangement with other dielectric materials. Compared with traditional photonic crystals, plasmonic photonic crystals have special properties such as anomalous refraction and time-varying dynamic controllability. Based on the above characteristics, plasmonic photonic crystals can be used in many electromagnetic wave control fields such as plasma antennas, optical switches, and plasma stealth, and have broad application prospects. [0003] The periodicity of conventional plasmonic photonic crystals is generally artificially fixed, usually by fabricating a dielectric rod array or an air hole array on...

Problems solved by technology

These plasmonic photonic crystals are alternately arranged with different refractive indices to form superlattice plasmonic photonic crystals, but relatively speaking, the structure is still slightly simple, which cannot meet the applications in some special fields.
