摘要

提出了一种利用圆形金属波导在喇叭天线中产生轨道角动量无线电波的新方法。在环形金属波导中，由两个TE21模式组合产生OAM模式。由此产生的电场分布和辐射模式证明了携带OAM的波的性质。研究了喇叭结构对所产生的OAM波特性的影响。

Generation of radio orbital angular momentum (OAM) waves with circular metallic waveguide

We present a novel way to generate radio waves bearing Orbital Angular Momentum (OAM) in the horn antenna by using a circular metallic waveguide. The OAM mode ℓ = 1 is generated by combination of two TE21 modes inside a circular metallic waveguide. The resulting electrical field distribution and the radiation patterns evidence the properties of waves carrying OAM. The influences of the horn structure on the properties of the generated OAM waves are also studied.
