Abstract

A resistive metasurface featured by the Rossler chaos reaction-diffusion system patterns is proposed and realized in a wideband electromagnetic absorber. The chaos surface consists of units with both random shapes and dimensions. Simulation results show absorption phenomenon, and correlation function analysis indicates new wave-Absorbing mode can be generated when correlation of the edges of the chaos patterns matches geometrical size of chaos units. Experimental results indicate unconventional bandwidth ratio with reflectivity lower than-10,-15, and-19 dB reaches 96.84%, 80.1%, and 56.1%, respectively. A high-Absorption nature makes this structure have application potential in a modern anechoic chamber or other electromagnetic wave absorbers.
