摘要：

The simplified multireflection interference theory is proposed to analyze the physical insight quantitatively of the ultra-broadband metamaterial absorber (MMA) loading lumped resisters in which the resonant layer, including lumped resisters and the substrate, are equivalent to a homogeneous and isotropic effective medium. The simulated full width at half maximum (FWHM) absorption bandwidths is approximately 11.2 GHz with relative FWHM absorption bandwidths of 116.7% for a normal incidence electromagnetic wave. Microwave experiments are performed and measured results are in good agreement with the numerical results. The absorbance of the proposed MMA calculated by the simplified multi-reflection interference theory coincides well with simulated and measured results.
