Study On The Nanostructure Of Optical Propulsion Based On Surface Plasma

With the development of aerospace technology,miniaturized satellite technology has become an important trend in contemporary satellite.In the miniaturized process,the propulsion system is the key point of design.The technology based on surface plasma optical array structure can provide piene satellites the required force to maintain a stable attitude,orientation and trajectory correction.Because of its light weight,zero power consumption,high specific impulse and other advantages,the optical array structure thruster has become one of the hot researches at home and abroad.This paper mainly consists of the following parts:This paper introduces the research background and the significance of the propeller.Starting from the point of view that light force on the particle's,this leads to the study of light propulsion mechanism array,indicating that the current light propulsion problems.Secondly,describes the basic principle of plasma thruster which based on enhanced light coupling of metal/dielectric structure.By the comparative analysis of two kinds of non-symmetric structure(isosceles trapezoid,trapezoid ladder structure)light field coupling strength,field simulation of gradient distribution of the two,acquire the best performance of the light propulsion structure array.From the theory,two important parameters are calculated by formula of the light propulsion array structure,specific impulse and thrust.Compared with the mature development of electric propulsion and chemical thrusters,the light propeller has zero power consumption,light quality,small volume,high specific impulse and other advantages.At the same time,we also pointed out that the light propulsion technology is difficulty and immature,thrust is relatively small,and is still in the discussion stage and principle test.This paper introduced the preparation process of light to promote the array,made the smallest size light propulsion array structure in the world and the characteristics of the nanoparticles are characterized.At the same time,the nanoparticles used for light propeller preparation are prepared.The light array thruster detection method is given at the end of the paper.The contribution of this dissertation is summarized,based on the development trend of light propeller at home and abroad and the problems existed in current scientific research,we prospect the next step of the research on surface plasmon based optical thruster.
