| 摘 要： | 激光等离子体通道天线被等效为电子在横向旋转、轴向漂移的均匀冷磁化等离子体束，且该等离子体束的横截面为沿轴向不改变的圆形。在考虑离心力、科里奥利力等惯性力的影响下，结合麦克斯韦方程和本构关系，得出了激光等离子体通道天线的散射场。为了简化，计算了一特例，发现了一些有趣的现象。

| Abstract: | The laser plasma channel antenna is equivalent to uniform cold magnetized plasma beam, which is assumed to be gyrating transversely and drifting longitudinally. The cross-section of the plasma beam is considered as circle and the shape is not changeable along with axis. Taking into account the influence of inertia force such as centrifugal force and Coriolis force etc, the EM scattering field of laser plasma channel antenna is derived from Maxwell equations and constitutive relations, and then an example is calculated and some interesting phenomena are discovered. |
