From: Enhanced absorption in all-dielectric metasurfaces due to magnetic dipole excitation
(a) The calculated transmission \({\mathscr{T}}\), reflection \({\mathscr{R}}\) and absorption \({\mathscr{A}}\) coefficients for the silicon metasurface on the borosilicate glass with the structure parameters as indicated in Fig. 1. The contribution of the MD moment is presented (similar to the b) as the dashed line for the convenient comparison. (b) The absolute values of the multipole contributions to the electric field amplitude \(({{\bf{E}}}_{0}^{sca})\) scattered by the metasurface. (c) The phase spectra of the absolute values of the contributions of the TED, MD and EQ moments calculated for n = (0, 0, 1). The area of the broadband absorption by the metasurface (compared to the thin film) is enclosed in the blue box bounded by the dashed line.
