Comments on “Wideband Microwave Absorber Comprising Metallic Split-Ring Resonators Surrounded With E-Shaped Fractal Metamaterial”

Recently, R. M. H. Bilal <italic>et al.</italic> proposed a wideband microwave absorber based on metallic split-ring resonators and an E-shaped fractal structure. It is found that the reflection components of high-order modes are very large but have been neglected by the authors. Our res...
