Abstract

Two kinds of fluorides are proposed innovatively to modulate the dielectric property of the plasma by reducing the electron density. There is a maximum of 74.41% electron density reduction after the fluorides are injected into the plasma at a magnitude of 1019 m−3, and the corresponding plasma frequency reduction is 49.42%. The fluorides proposed in this paper exhibit a wider modulation range, a faster modulation speed, and a longer maintenance time compared with SF6. The electromagnetic (EM) wave transmission characteristics in plasma are modulated correspondingly. The attenuation of S21 is reduced by 15.11–20.11 dB in 6–18 GHz, and an enhancement in the whole experimental frequency range is observed compared with SF6. The results of the paper can be applied in the mitigation of reentry vehicle's EM wave attenuation induced by the over-dense plasma sheath covering the vehicle. In addition, it also has a potential in broad applications of EM wave and plasma interactions.

利用氟化物控制电子密度以调节气态放电等离子体的介电特性
创新性地提出了两种氟化物,通过降低电子密度来调节等离子体的介电性质。将氟化物注入量级为 1019 m-3 的等离子体后,电子密度最大降低了 74.41%,相应的等离子体频率降低了 49.42%。与 SF6 相比,本文提出的氟化物具有更宽的调制范围、更快的调制速度和更长的维持时间。等离子体中的电磁波传输特性也相应得到调制。在 6-18 GHz 频率范围内,S21 的衰减降低了 15.11-20.11 dB,与 SF6 相比,在整个实验频率范围内都有增强。本文的研究结果可用于减轻再入飞行器上覆盖的过密等离子体鞘引起的电磁波衰减。此外,它还具有广泛应用于电磁波和等离子体相互作用的潜力。
