Graphical Abstract
In article no. 1900069 by Shijun Ji et al., a polarizationinsensitive ultra-broadband metamaterial absorber (UMMA) is proposed. The UMMA's unit cell consists of a metal film and a multilayer-crosscone structure separated by a dielectric layer. Through a larger number of calculations, analysis and optimization from physical parameters of electromagnetic wave and structural parameters on the absorber, optimized parameters for the unit cell are obtained. The UMMA is polarization-insensitive for normal incident wave and its absorptivity is more than 96% in the entire X-band (8-12 GHz).
