RADIO WAVE ABSORPTION PANEL
PURPOSE:To acquire high reflection loss in a wide band region and to make possible reduction of manufacturing time and weight in a radio wave absorption panel. CONSTITUTION:The radio wave absorption panel is constituted of an armor material 1 such as granite, a ferrite board 2, an air layer 3 and a...

description | PURPOSE:To acquire high reflection loss in a wide band region and to make possible reduction of manufacturing time and weight in a radio wave absorption panel. CONSTITUTION:The radio wave absorption panel is constituted of an armor material 1 such as granite, a ferrite board 2, an air layer 3 and a metallic reflection board 4 one by one from outside in the direction of coming radio waves. The ferrite board 2 of the panel is almost continuous in a magnetic field direction of radio wave and arranged discontinuous in a field direction, and the width of the air layer 3 between the ferrite board 2 and the metallic reflection board 4 is 30 to 300mm. |
