| 摘 要： | 由于实验无法准确测量螺旋带上的面电流分布，在详细比较理论分析与软件模拟异同的基础上，应用3维电磁场计算软件HFSS研究了螺旋带相对宽度与面电流分布的关系。研究表明：螺旋带相对宽度越大，面电流分布越不均匀；当Floquet边界的相位移为90°时，面电流分布最不均匀；面电流分布的均匀性假设在不同频率下有不同的准确程度。

| Abstract: | Based on the difference between theoretical analysis and soft model, the effect of the ratio of the tape width to helix pitch on the surface current distribution of the tape helix was simulated using 3-D simulation software HFSS. It is found that the bigger the ratio is, the more asymmetric the surface current distribution is. While the phase shift of the Floquet boundary is 90°, the surface current distribution is the most asymmetric. Under different frequencies, the accuracy of the uniformity assumption of the surface surrent distribution is different. |
