From: A Low-loss Metasurface Antireflection Coating on Dispersive Surface Plasmon Structure
The real (red) and imaginary (blue) parts of (a) effective permittivity εeff and (b) permeability μeff of the MDA metasurface. Inset shows the real part of effective permittivity, Re(εeff) (red) and the loss tangent, tan δ (green). (c) Diagram of the reflection and transmission coefficients of MDA and MHA. (d) Reflections obtained by full-wave simulation of actual MDA-BCB-MHA (black line), analytical calculation (blue line) using Eq. 1 and full-wave simulation of metafilm-BCB-MHA structure with wavelength-dependent (red dash line) and wavelength-independent (green dash-dot line) effective parameters. (e) The amplitude and phase (f) terms in the AR conditions (Eqs 2 and 3).
