Abstract :
Transmission coefficients predicted by modal analysis agree well with measurements, but an LC equivalent circuit gives satisfactory results for normal incidence only. The two methods predict similar phases for the induced currents. The modal method´s account of the current distribution is illustrated for two resonant frequencies in the E-plane.
