Abstract

This paper proposed a FDTD method to calculate the surface current distribution on the microstrip conductor. The algorithm is deduced, and the distribution by this method is well agreed with the finite element method and the analytical one. And we also calculated the normalized current density ratio on upper and lower surface of the conductor. We find that the ratio decreases while the width of the conductor increases. This current distribution calculation method is easy to program, and can be used on the nonlinearity research of high-temperature superconductor planar circuits.
