High-Performance and Flexible Metamaterial Wave Absorbers with Specific Bandwidths for the Microwave Device

In this paper, we proposed a high-performance electromagnetic-wave metamaterial absorber which can be used directly for 5G technology. The exhibits high performance in tailored frequency range of 28 ± 1 GHz. At both transverse-electric and transverse-magnetic polarization, the absorption exceeds 99% when electromagnetic wave is incident normally, keeps being over 97% as angle increases even to 45 degrees. flexible, it very suitable mass production because process simple. addition, minimum dimension meta-structure only 0.2 mm, cost relatively low. Similarly, another with bandwidth at center 77 GHz, relevant self-driving cars, was also prepared by minimal adjustment original structure.
