Novel plasma photonic crystal omnidirectional reflector and implementation method

Abstract

The invention discloses a novel plasma photonic crystal omnidirectional reflector and an implementation method. The omnidirectional reflector includes a dielectric layer and a plasma layer. The plasmalayer comprises an excitation electrode and an inert gas inside the excitation electrode, the generation of the plasma is excited by an excitation source controlled by a programmable logic array, andthe magnitude of the excitation voltage can also be controlled through the programmable logic array; the dielectric layer comprises two media with different dielectric constants, namely, quartz and air. The plasma layer, the quartz layer and the air layer are used for forming a laminated structure, and an all-directional reflector based on a one-dimensional plasma photonic crystal is formed by taking a nested fractal sequence as a rule in an iterative manner. The one-dimensional plasma photonic crystal all-directional reflector based on the nested fractal structure has the characteristics oflarge working bandwidth, easy tuning, compact structure, easy integration.

Description

technical field [0001] The invention relates to a novel plasma photonic crystal omnidirectional reflector and its implementation method, in particular to a tunable broadband one-dimensional plasma photonic crystal omnidirectional reflector based on a nested fractal structure and its implementation method, belonging to electronic communication, Microwave device technology and plasma practical technology field. Background technique [0002] With the development of information technology, electromagnetic waves play an increasingly important role in the process of information transmission. Various microwave devices in communication systems have increasingly strong requirements for reflective mirrors, such as planar reflectarray antennas, reflectors for absorbers, special function waveguides, filters, and planar mirror reflectors. [0003] However, traditional metal reflectors have been difficult to meet the requirements of functional devices in the modern communication field, s...

Problems solved by technology

However, omnidirectional reflectors composed of conventional media generally have shortcomings such as narrow operating bandwidth and inability to perform wide-range tuning in the operating frequency domain.

This largely limits the application of photonic crystal directional reflectors
