不均匀磁等离子体的隐身机理——圆极化电磁波的碰撞吸收

研究了圆极化电磁波在不均匀磁等离子体的传播和吸收。讨论了不均匀磁化等离子体片对平行于磁场方向传播的左、右旋圆极化电磁波的碰撞吸收，计算了不同条件下衰减率。计算表明，当电磁波的频率接近电子碰撞频率时，磁等离子体对电磁波的吸收达到最大值。当入射电磁波的频率很低时，不均匀磁化等离子体中磁撞对雷达波的吸收非常小。当入射电磁波频率较高时，等离子体的碰撞对入射电磁波的衰减很有效。

Research on the collisional absorption of the right circularly polarized wave and the left circularly polarized wave by inhomogeneous magnetized plasmas

A variety of stealth technology of inhomogeneous magnetized plasma is presented in this paper. The collisional absorption of the right circularly polarized wave and the left circularly polarized wave propagating parallel to the magnetic field by inhomogeneous magnetized plasmas is discussed, and the attenuations are calculated under different conditions. The results illustrate that the collisional absorption have a maximum value when the collision frequency is near the radiation frequency. Meanwhile, the absorption is very poor when the EM wave frequency is small, and the absorption is efficient with a high incident EM wave frequency.
