Abstract

PURPOSE: To absorb an incoming radio wave from outside to prevent a reflected wave from generating to the utmost, and to prevent disused waves from leaking out of the inside of a building, by installing a needed number of movable units in the lower end of a panel body which comprises a wave absorbing face having a ferritic molding on one side and an electromagnetic shielding face of a metallic conductor on the other side.
CONSTITUTION: A wave absorbing panel body 1 comprises a wave absorbing face 1a on one side and an electromagnetic shielding face 1b on the other side. The wave absorbing face 1a is comprised of a metallic reflecting plane 2 in the inside thereof which reflects a television wave with a frequency band to be objective, and a ferritic molding 3 which is bonded on the outside of the metallic reflecting plane 2 and has a function to absorb the television wave. And the electromagnetic shielding face 1b is comprised of a metallic reflecting plane 4 which has a reflecting characteristic for a wave with a large frequency band. A movable units 5 which are installed in the lower end of the panel body 1 so as to be easily rolled changing the traveling direction thereof freely, which makes the body 1 movable easily. When this panel is located within a room of a building whose exterior wall allows a wave to pass through, the wave absorbing face 1a absorbs the incoming wave from outside while the electromagnetic shielding face 1b prevents disused radio waves from leaking out of the inside of the room.
