<p>PURPOSE: An electromagnetic wave reverberation chamber is provided to variously control an electromagnetic wave reflection characteristic inside. CONSTITUTION: A rectangular shape electromagnetic wave reverberation chamber(1400) have a specific distance from a metal conductor of a first wall surface(1410) inside. The first wall surface adjusts length downward from the top of the wall to the bottom or a specific part while making a width of an electromagnetic wave absorption film be a desired size. An electromagnetic wave absorption film roll having the other width is installed in the other wall surface. An electromagnetic wave absorption structure being as a roll screen shape includes a roll winding one edge of the electromagnetic wave absorption film installed in the top of the first wall surface with the predetermined width and a film fixing apparatus fixing the other edge of the electromagnetic wave absorption installed in the lower part with the same width as a cover covering this film roll. [Reference numerals] (1410) First wall surface; (AA) Width of an electromagnetic wave absorption film; (BB) Electromagnetic wave absorption film roll; (CC) Electromagnetic wave absorption film; (DD) Fixing device for an electromagnetic wave absorption film; (EE) Cover for an electromagnetic wave absorption film roll; (FF) Stirrer; (GG) Ceiling surface; (HH) Second wall surface; (II) Floor surface; (JJ) Fourth wall surface; (KK) Third wall surface</p> |
