摘要: 本文通过实验和数值模拟研究了等离子体丝对微波传输的影响，研究了微波入射角度和等离子体丝间距对微波反射率的影响。结果表明，当微波入射面与细丝传输方向垂直，S极化入射时，微波的反射率随着入射角度的增加而迅速增大；当微波入射面与细丝平行，P极化入射时，反射率随入射角度增加而逐渐减小。此外，减小等离子体丝间距可以使微波的反射率增加。
Abstract: The effects of femtosecond filaments on microwave transmission are studied by experiments and numerical simulations, including the influences of incident angle of the microwave and separation distance of filaments on microwave reflection coefficient. The results indicate that when the plane of the incident microwave is perpendicular to the propagation direction of the filaments, the reflection coefficient increases with the increase of the incident angle of S-polarized microwave. When the plane of the P-polarized incident microwave is parallel to the filaments, the reflection coefficient decreases as the incident angle increases. Besides, the reflection will be enhanced by reducing the separation distance between the filaments.
