| 摘 要： | 研究了电子回旋波在均匀磁等离子体的传播和吸收,讨论了不同的入射波垂直进入均匀磁等离子体的吸收衰减情况.计算表明,当波的频率接近等离子体中的电子回旋频率时,磁等离子体对波的吸收达到最大值.当入射波的频率增加时,均匀磁等离子体对波的衰减随入射波频率的增加而减小,并伴随着等离子体密度的增大,磁等离子体对波的衰减在增大.

| Abstract: | The propagation and Absorption of electron cyclotron wave in homogeneous magnetized plasma is investigated in this paper.The wave propagating perpendicular to the magnetic field by homogeneous magnetized plasmas is discussed,and the attenuations are calculated under different conditions.The results illustrate that the collisional Absorption reaches a maximum value when the collision frequency is near the radiation frequency.With the increase in the frequency of electromagnetic wave and density,the attenuation increases. |
