Fig. 6: Switchable design and dynamic absorption performance.
From: Chainmail-inspired conformable and switchable microwave metamaterial absorber
a Schematic of the frequency-switchable absorption system (Gray arrows indicate the direction of movement for the locating pins). b Expansion and contraction process of the absorber (with a step size of 1 cm for the side length). Green represents the areas that have not yet moved during expansion, while red represents the areas that have not yet moved during contraction. c Simulated reflection loss heatmap of the absorber with uniformly varied side lengths. d Loss distribution for contraction and expansion states at 5.5 GHz and 8 GHz. e Effective permittivity of the absorber with different side lengths. f Effective permeability of the absorber with different side lengths. Measured reflection loss of the absorber with different side lengths during expansion (g) and contraction (h).
