  • Electromagnetic wave blocking device having electromagnetic wave shielding and absorbing capacity and manufacturing method therefor
    Patent number: 10667443
    Abstract: The present invention provides an electromagnetic wave blocking device having electromagnetic wave shielding and absorbing capacity. The electromagnetic wave blocking device having electromagnetic wave shielding and absorbing capacity includes: an electromagnetic wave blocking device body part configured such that an identical material is mixed with shielding and absorbing materials or different materials are arranged on both sides of a boundary of their sides to thus enable electromagnetic wave absorption and electromagnetic wave shielding; and an edge electromagnetic wave absorbing part formed along the boundary of the blocking device body part to thus additionally block electromagnetic waves. Furthermore, the present invention provides a method for manufacturing the electromagnetic wave blocking device.
