13Abstract of the Disclosure:For effectively suppressing echo of anelectromagnetic wave emitted from an electromagneticdevice (24) disposed in a closed space (13) which isdefined by a shielding wall (10), an electromagneticanechoic chamber comprises an absorption member (28)disposed in the space. The wall has an inner surfacewhich reflects the electromagnetic wave into the spaceas a reflected wave. The reflected wave is directed toa particular position in the space. The absorptionmember is located at the particular position.Preferably, the inner surface is formed along asubstantially ellipsoidal shape having a first and asecond focus point (14, 16). The electromagnetic deviceand the absorption member are located at the first andthe second focus points, respectively.
