补充资料:波束波导
波束波导 beam waveguide 由周期性排列的透镜或反射镜组成的波导结构。由于透镜或反射镜的聚束作用, 被导引的电磁波集中在横截面较小的区域内以波束形式传播。波束的电磁场分布沿传播方向呈周期性变化,沿径向坐标ρ按高斯函数变化(α为常数),故又称为高斯型波束。透镜型波束波导由焦距为f的介质透镜按间距2f共轴排列组成。波束以 2f为周期重现。单反射镜型波束波导用焦距为2f的椭圆面按相邻椭圆面共焦的方式排列,从焦点a发出的波束,由椭圆面1反射到2再反射到3……,波束沿锯齿形路径传播。双反射镜型波束波导由两块平板和两个抛物面组成。从F1发出的球面波,由平板1反射到抛物面2变成平面波,传播到抛物面3后变成球面波,再由平板4反射到F2,使波束重现。不同类型的波束波导有不同的传输损耗和不同的频率适用范围。介质透镜型适用于光波,双反射镜型适用于微波,单反射镜型适用于毫米波和亚毫米波。高斯波束可用波纹圆锥喇叭作激发器。 |
