摘要
基于无衍射光束理论,采用P-B相位原理,本文提出了两款特殊波形生成器。通过设计具有透射相位可调特性的电磁结构,按照OAM和贝塞尔补偿相位分布要求对上述结构进行周期性布阵,在15GHz的平面波照射下发生奇异透射现象,从而研制出平面波-OAM波束生成器和平面波-无衍射贝塞尔波束生成器。该结构具有超薄和高透射率的特点,易于加工。本文为无衍射电磁波和OAM波束的生成提供了有效的方法。
Based on the theory of non-diffracted beams and the principle of P-B phase,this paper proposes two special waveform generators.By designing an electromagnetic structure with adjustable transmission phase characteristics,periodically arranging the above structures in accordance with the OAM and Bessel compensation phase distribution requirements,the singular transmission phenomenon occurs under the 15 GHz plane wave irradiation,thereby developing a plane wave-OAM beam generator and a plane wave-non-diffractive Bessel beam generator.The structure has the characteristics of ultra-thin and high transmittance,and is easy to process.This paper provides an effective method for generating non-diffractive electromagnetic waves and OAM beam.
