Fig. 5: Conformal absorption performance on complex curved surfaces.
From: Chainmail-inspired conformable and switchable microwave metamaterial absorber
a Structural comparison between the chainmail absorber and three conventional absorbers on semi-cylindrical surfaces. b Comparison of the monostatic RCS of a metal semi-cylindrical surface (height: 295 mm, radius: 93 mm) before and after being covered by the absorber. c Comparison of the 3D bistatic RCS simulation results of a metal semi-cylindrical surface before and after being covered by the absorber. d Comparison of the measured absorption bandwidth of the chainmail absorber with full-size, equivalent medium, and conventional absorbers’ simulation results. e Comparison of the measured average absorptivity of the chainmail absorber at different frequency bands with full-size, equivalent medium, and conventional absorbers’ simulation results. Photographs of the absorber conformal to a saddle surface (f) and a spherical (two convex and two concave)-planar combined surface (g), with insets showing the Gaussian curvature distribution. Comparison of the monostatic RCS of a metal saddle surface (h) and a metal spherical-planar combined surface (i) before and after being covered by the absorber.
