(a) Simulations (open circles) and calculations (solid lines) for the reflection amplitude |r| of HPMA structure at different dielectric thickness S. (b) The absorptive factor \(Q_a\) and radiative factor \(Q_b\) with versus S obtained by CMT-fitting. The inset displays the enhancement of microwave magnetic field distribution on Py stripe position at resonant frequency of the HPMA. The simulated (open circles) and calculated (solid lines) phase results at (c) S = 0.01 mm, (d) S = 0.24 mm, and (e) S = 1.6 mm corresponding to over damping, critical damping and under damping, respectively.
