In this paper, near zone scattering properties of a perturbed perfect electromagnetic conductor (PEMC) cylinder are observed using the perturbation theory (PT). The analytical solution of the scattered field is obtained for both the transverse electric (TE) and transverse magnetic (TM) polarizations of the incident field. The perturbed cross section is generated considering the limits imposed by the PT. The effect of perturbations on the co and cross polarized components of the scattered field from a perturbed PEMC cylinder is observed and compared with the reference scattered field from the circular PEMC cylinder. In particular, the distinctions due to perturbations are observed in the forward and backward scattering. The forward scattering deviates more than the backward scattering. Also, the effect of perturbations for the TE polarization is more evident. The variations in the co and cross polarized scattering are also noted by changing the value of the admittance of the PEMC cylinder.

在本文中，使用微扰理论 (PT) 观察了微扰完美电磁导体 (PEMC) 圆柱体的近区散射特性。散射场的解析解是针对入射场的横向电 (TE) 和横向磁 (TM) 极化获得的。考虑到 PT 施加的限制，会生成扰动横截面。观察扰动对来自被扰动的 PEMC 圆柱体的散射场的 co 和交叉偏振分量的影响，并与来自圆形 PEMC 圆柱体的参考散射场进行比较。特别是，在前向和后向散射中观察到由于扰动而产生的差异。前向散射比后向散射偏离更多。还，TE 极化扰动的影响更为明显。通过改变 PEMC 圆柱体的导纳值，还可以注意到 co 和交叉偏振散射的变化。
