Abstract

The present invention provides a device and a method capable of generating a stable and continuous plasma photonic crystal. The device comprises an array liquid electrode and a plane liquid electrodewhich are oppositely arranged, a plurality of channels filled with conductive liquid are distributed in an array mode on the array liquid electrode in an insulating base body, the conductive liquid ineach channel is connected with an electrode wire, the two ends of the insulating base body are respectively provided with medium baffles closing the channels, the electrode wires pass through the medium baffle at one end of the insulating base body and are connected with a discharge power source, the medium baffle at the other end of the insulating base body is arranged oppositely in parallel with the plane of the plane liquid electrode to form a discharge gap, and the plane liquid electrode is a grounding electrode. The device and the method capable of generating the stable and continuous plasma photonic crystal can achieve long-time and continuous existence of the plasma photonic crystal and can perform time periodic modulation for the plasma photonic crystal on the [mu]s order so as tomeet the long-time stable control of the electromagnetic waves with different wave bands.

Description

Technical field [0001] The invention relates to the technical field of plasma application and optics, in particular to a device and method that can generate stable and continuous plasma photonic crystals. Background technique [0002] As a new type of photonic crystals, plasma photonic crystals have received extensive attention from scholars at home and abroad in recent years, and are expected to be used in many electromagnetic wave control fields such as filters, optical switches, plasma lenses, and plasma stealth. Plasma photonic crystal is a periodic structure formed by the periodic distribution of plasma density or staggered arrangement with other dielectric materials. It not only has the band gap structure of conventional photonic crystals, which realizes the control of light propagation in a certain band, but the most prominent advantage is the temporal and spatial tunability of the band structure. People can change the plasma parameters by adjusting the external drive, an...
