Abstract

The invention discloses a preparing method of the micro / sub-micron ferrule and the open ferrule. It gets the two-dimensional colloid crystal by the self-organizing technology, then to anneal in high temperature, chemical corruption, the secondary anneal in high temperature to form the non close-packed two-dimensional structure; the polymer is filled into lattice space to form the compound film which is put in the hydrofluoric acid steam to go on the secondary corrosion and form the ring space; the surface of the compound module is spurted by metal, then to resolve the compound module to get the ferrule array structure. If the sample is dipped into the alcohol solution to make the ring space change the partiality ring space; then to spurt by metal and remove the compound module to get the open ferrule. The advance of the invention is: the structural parameter can be controlled; the inner and outer diameter of the ferrule and the open ring can be adjusted and the circle can be controlled; the single disperse character is good and the thickness is uniform; the interface is clear and the technology is simple.

Description

technical field

[0001] The invention relates to a preparation method of a two-dimensional ordered micron / submicron metal ring and an artificial magnetic metamaterial formed by a two-dimensional ordered array of the micron / submicron open metal ring. Background technique

[0002] The preparation technology of two-dimensional ordered micro / submicron metal rings and split metal rings is a technology with important application background. Due to the tunable plasmon resonance of micron / submicron metal rings, the magnetic response of micron / submicron split metal rings and other novel electromagnetic properties, micron / submicron metal rings and split rings are widely used in optical devices, high-density storage, negative Areas such as refractive materials have potential applications. At present, the methods for preparing micron / submicron metal rings and split rings mainly include photolithography, electron beam or ion beam etching, focused ion beam direct writing, microcontact pri...
