Electromagnetic shielding performance measurement chamber and the electromagnetic wave shielding performance measurement method

摘要

PROBLEM TO BE SOLVED: To provide an electromagnetic wave shielding performance measurement chamber and an electromagnetic wave shielding performance measurement method, capable of eliminating carrying-in and carrying-out of an object to be measured, capable of performing measurement extremely economically when the object is present at a close distance and specifically the object is a large member, also capable of performing highly accurate measurement by suppressing an electromagnetic wave from reflecting or sneaking, and further capable of performing highly reliable measurement by also preventing a radio wave from entering from the outside.;SOLUTION: An electromagnetic wave shielding performance is measured by forming a rectangular prism measuring chamber using a movable electromagnetic wave absorber 1 including an electromagnetic wave absorber erected on a movable truck, an object C to be measured, and a floor surface absorber 2 provided on a floor surface or a ceiling plane.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2016,JPO&INPIT
