摘要

提出了一种利用圆波导产生轨道角动量无线电波的新型喇叭天线。利用圆波导内的螺旋相板(SPP)产生了OAM模式(r = 1)。本文提出了两种将经典导模转换为OAM波的方法。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。

Horn antenna for generating Orbital Angular Momentum (OAM) waves

We present a novel horn antenna to generate radio waves bearing Orbital Angular Momentum (OAM) by using a circular waveguide. The OAM mode ℓ = 1 is generated by using a spiral phase plate (SPP) inside a circular waveguide. We present here two methods to transform the classical guided modes to OAM wave. The resulting electrical field distribution and the radiation patterns evidence the properties of waves carrying OAM.
