摘要

等离子体被称为物质的第四种状态,它与固体、液体和气体有许多不同的特性。这些特性在低温等离子体领域具有广泛的应用前景。在低温等离子体领域,有材料表面改性、医药等。利用avantes 2048L发射光谱仪测定了常压下锌等离子体的密度。结果表明,随着输入功率的增大,电子温度和电子密度逐渐增大,但光谱强度相应减小。然后利用有限元电磁仿真软件HFSS对等离子体射流的电磁分布进行分析,发现等离子体表面的电磁波为行波。

Application of Finite Element Simulation Method in Measurement of Zinc Plasma Parameters
The plasma is called the fourth state of matter, which has many different properties from solid, liquid and gaseous. These properties can be widely used in the field of low temperature plasma. In the field of low temperature plasma, there are material surface modification, medicine and so on. We use the emission spectrometer avantes 2048L to enter the density of zinc plasma at atmospheric pressure. It is found that with the increase of input power, the electron temperature and density increase gradually, but the spectral intensity decreases accordingly. Then we use the finite element electromagnetic simulation software HFSS to analyze the electromagnetic distribution of plasma jet, and find that the electromagnetic wave on the plasma surface is traveling wave.
