Power ratio, , as a function of normalized frequency (2), computed from 2D finite-element simulation results. Four data sets are compared: three with different characteristic frequencies (data sets 1, 3, and 4) and two with the same but different configuration parameters (data sets 1 and 2), all with the number of layers .
The power ratio, , obtained from 2D finite-element simulations (dots) compared with that computed by Eq. (3) (solid line). The dashed line shows the computed values for infinite . Normalized frequency is defined by Eq. (2).
Comparison of measured imaginary component of permeability to the results from different models: the new model [Eq. (3)], the simple model [Eq. (1)], and the single-layer model . The raw data are measured . The adjusted data have the estimated subtracted off. The tested material has and =599 MHz.
