Variation of relative magnetic field magnitude \(|\textbf{H}|/|\textbf{H}_\textrm{inc}|\) along axis z for: (a) Ag-based designs and (b) Si-based designs, operated at three different colors of the optical wavelengths \(\lambda\), as indicated by the respective color of the curves. Maximum \(\textrm{Re}[\beta /k_0]\) bilayers are used from Table 1. Vertical black dashed lines denote the interface in-between the two media while colored dashed lines correspond to the front boundary of the used semiconducting slab.
