Metasurface Perfect Absorber: Standing-Wave & Γ-Plane View

2D standing-wave and complex reflection-plane view of a Salisbury-screen metasurface absorber: tune sheet resistance, spacer thickness, permittivity and frequency and watch the standing wave in front of the sheet flatten, and the reflection coefficient collapse to the origin, exactly at perfect impedance match.

The 2D companion to the layered-stack metasurface absorber: instead of a rendered 3D box, this view plots the actual electromagnetic standing wave that forms in free space in front of the resistive sheet — the coherent sum of the incident and reflected travelling waves — alongside the absorption spectrum and the complex reflection coefficient's trace inside the unit circle. Tune sheet resistance, spacer thickness, permittivity and frequency and watch the standing-wave envelope flatten and the Γ-trace collapse to the origin exactly when the surface reaches the classic Z_s = Z₀, d = λ/4 matching condition.
