Abstract
The disclosure discloses a wide-frequency wave-absorbing metamaterial, which comprises a plurality of layers of substrates and microstructures respectively arranged on the substrates at different layers. The wave-absorbing frequency band of the wide-frequency wave-absorbing metamaterial is relatively wide. The disclosure further discloses an electronic device and a method for obtaining a wide-frequency wave-absorbing metamaterial. By using the foregoing manner, the disclosure can enable a wave-absorbing metamaterial to significantly increase a wave-absorbing bandwidth based on a relatively good electromagnetic wave absorbing effect.
