Electromagnetic wave reverberation chamber

1. An electromagnetic wave reverberation chamber, comprising:

a column-type mode stirrer including a plurality of plate-shaped electromagnetic wave reflectors connected by a metal column provided on a bottom of the electromagnetic wave reverberation chamber;

a ceiling-type mode stirrer including a plurality of plate-shaped electromagnetic wave reflectors connected by a metal column provided on a wall surface of the electromagnetic wave reverberation chamber, and disposed around a ceiling of the electromagnetic wave reverberation chamber;

a pyramidal mode stirrer including a plurality of pyramid-shaped electromagnetic wave reflectors and disposed on a wall surface of the electromagnetic wave reverberation chamber, and

a concavo-convex mode stirrer including an electromagnetic wave reflector disposed in a concavo-convex form, and disposed on another wall surface different from the wall surface on which the pyramidal mode stirrer is disposed,

wherein the concavo-convex mode stirrer is provided as a plurality of concavo-convex mode stirrers disposed parallel to the wall surface, each concavo-convex mode stirrer having a width parallel to the wall surface greater than a height extending from the wall surface, and

wherein each of the column-type mode stirrer and the ceiling-type mode stirrer is formed by a combination of at least two panels.

2. The electromagnetic wave reverberation chamber of claim 1 , wherein an eigenmode of the electromagnetic wave reverberation chamber is changed by the column-type mode stirrer, the ceiling-type mode stirrer, and the pyramidal mode stirrer.

3. The electromagnetic wave reverberation chamber of claim 1 , wherein an eigenmode of the electromagnetic wave reverberation chamber is changed by adjusting a width, a length, and a height of the concavo-convex mode stirrer, and a number of concavo-convex mode stirrers.

4. The electromagnetic wave reverberation chamber of claim 1 , wherein the plurality of plate-shaped electromagnetic wave reflectors of each of the column-type mode stirrer and the ceiling-type mode stirrer are combined to form a preset shape.

5. The electromagnetic wave reverberation chamber of claim 4 , wherein a size of each of the plurality of plate-shaped electromagnetic wave reflectors is determined to be a preset value.

6. The electromagnetic wave reverberation chamber of claim 4 , wherein a gap between the plurality of plate-shaped electromagnetic wave reflectors is determined to be a preset value.
