| 摘要 |
The present invention relates to meta-atoms capable of absorbing electromagnetic waves at specific frequency bands of incident electromagnetic waves, and to a metal-material comprising the same. Since the meta-atoms according to the present invention are designed as meta-atoms having a size corresponding to 1/30 of the wavelengths of incident electromagnetic waves, the meta-atoms are very simple to manufacture at low-frequency bands including MHz bands, enable complete absorption, are flexible and thus are easy to install, so that the meta-material comprising the meta-atoms can be used in various fields, such as an absorber or like, capable of completely absorbing electromagnetic waves which are generated by various kinds of electronic devices including a mobile phone and are harmful to the human body. Furthermore, the meta-atoms of the present invention can be manufactured with only conductors and dielectrics, thereby reducing manufacturing costs of the meta-material. |
