基于ICP等离子装置的太赫兹波传输特性研究
Research on the Transmission Characteristics of Terahertz Waves Based on ICP Plasma Device
摘要
Abstract
The propagation characteristics of terahertz waves within hypersonic plasma sheaths are pivotal to advancing terahertz communication,measurement and control,and navigation technologies.To extend relevant research,based on an inductively coupled plasma simulation device,this paper uses terahertz time-domain spectroscopy(THz-TDS)method to design and implement experimental measurements of terahertz wave propagation characteristics within hypersonic plasma flow fields.It acquires and analyses the influence of plasma medium within the cavity on terahertz wave transmis-sion.Meanwhile,a combined approach utilizing Langmuir probes and theoretical simulations is employed to establish the three-dimensional electron density distribution within the cavity.Based on this model,electromagnetic simulation algorithms are applied to derive theoretical transmission results of terahertz waves,and theoretical and measured values are compared and verified.The results indi-cate that the experimental findings exhibit a high degree of agreement with theoretical calculations,when the plasma electron density generated by the inductively coupled plasma device reaches approxi-mately 1017 m-3.This demonstrates the feasibility of THz-TDS for investigating the electromagnetic properties of dynamic,high-temperature,and high-pressure non-uniform hypersonic plasmas.关键词
