摘要
激光等离子体通道天线是一种具有卓越隐身性能的新概念天线。简单阐述了激光等离子体通道天线的系统实现,建立了等离子体通道天线的分析模型,结合边界条件推导出分析电磁波沿激光等离子体通道传播特性的特征方程和分析电磁波沿激光等离子体通道表面向外辐射特性的天线表面波模式色散方程,从而计算了激光等离子体通道天线的传播特性曲线和辐射方向图,为新概念激光等离子体通道天线的实现打下坚实的基础。
As a new conception antenna,the laser plasma channel antenna has excellent stealth capability.The concrete realization method of the laser plasma channel antenna is simply described,and the analysis model of the laser plasma channel antenna is established.The rigorous characteristic equation for analyzing propagation properties and the surface-wave mode dispersive equation for analyzing radiation pattern of the laser plasma channel antenna are deduced separately by applying the boundary conditions of electromagnetic fields.The propagation property curves and radiation patterns of the laser plasma channel antenna are calculated,and it has set up a solid foundation for the practical application of this antenna.
