Abstract

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.
