By using Huygens-Fresnel diffraction integral formula and the transfer matrix method, the analytical expression of radially and azimuthally polarized chirped Airy-Gaussian vortex beams through left-handed materials and right-handed materials can be obtained. We study the effects of the chirp factor and the distribution factor on the radially and azimuthally polarized chirped Airy-Gaussian vortex beams in the propagation process, including the light intensity, the phase distribution, the propagation path, the peak intensity, and the radiation force. The focal position of the beams can be adjusted by the chirp parameter.
通过使用惠更斯 - 菲涅耳衍射积分公式和传输矩阵方法，可以得到径向和角向偏振啁啾艾里 - 高斯涡旋光束通过左手材料和右手材料的解析表达式。我们研究了啁啾因子和分布因子对径向和角向偏振啁啾艾里 - 高斯涡旋光束在传播过程中的影响，包括光强、相位分布、传播路径、峰值强度和辐射力。光束的焦点位置可以通过啁啾参数进行调节。
