Title:
ROOM STRUCTURE, METHOD OF MANUFACTURING WAVE ABSORBER, AND BUILDING
Document Type and Number:
Japanese Patent JP2010074098
Kind Code:
A
Abstract:
To provide a room structure that absorbs broad band electromagnetic waves, to provide a method of manufacturing a wave absorber equipped in the room structure, and to provide a building having the room structure.
A plane-part wave absorbing film 42 of a room structure 26 has a frequency characteristic to absorb only an electromagnetic wave P of an intrinsic frequency, which is different depending on the incident angle. Using this property, by repeatedly reflecting an electromagnetic wave P generated in the interior of a room 12 from wave reflecting layers 20A to 20D and making the wave incident on the plane-part wave absorbing film 42 in various incident angles, the broad band electromagnetic waves P can be absorbed.
