Query: Material-structure integrated design for ultra-broadband microwave
  metamaterial absorber   We propose herein a method of material-structure integrated design for
broadband absorption of dielectric metamaterial, which is achieved by
combination of genetic algorithm and simulation platform. A multi-layered
metamaterial absorber with an ultra-broadband absorption from 5.3 to 18 GHz (a
relative bandwidth of as high as 109%) is realized numerically and
experimentally. In addition, simulated results demonstrate the proposed
metamaterial exhibits good incident angle and polarization tolerance, which
also are significant criteria for practical applications. By investigating the
working principle with theoretical calculation and numerical simulation, it can
be found that merging of multiple resonance modes encompassing
quarter-wavelength interference cancellation, spoof surface plasmon polariton
mode, dielectric resonance mode and grating mode is responsible for a
remarkable ultra-broadband absorption. Analysis of respective contribution of
material and structure indicates that either of them plays an indispensable
role in activating different resonance modes, and symphony of material and
structure is essential to afford desirable target performance. The
material-structure integrated design philosophy highlights the superiority of
coupling material and structure and provides an effective comprehensive
optimization strategy for dielectric metamaterials.
