Electromagnetic Wave Absorber
First Claim
1. An electromagnetic wave absorber, comprising:
- element receiving means provided with a plurality of conductor elements having predetermined resonant frequencies and including a plurality of types of conductor elements that perform different receiving operations, the plurality of conductor elements being arranged spaced away from each other in a direction intersecting an incoming direction of electromagnetic waves, and the plurality of conductor elements being substantially polygonal and having at least one corner portion of an arc shape having a curvature radius corresponding to the resonant frequencies; and
a loss material for causing energy loss to electromagnetic waves, provided close to the element receiving means.

Abstract
A thin, light and soft electromagnetic wave absorber is disclosed exhibiting an excellent workability. The first conductor element group of a first conductor element layer consists of aligned cross conductor elements and square conductor elements in regions surrounded by cross conductor elements. A radio wave incident from the first conductor element layer side is received by each element, internally subjected to multiple reflection and then absorbed by a first loss material layer. Since the first conductor element group is realized by the cross conductor elements and the square conductor elements, receiving effect is enhanced and the radio wave can be collected with a high collection efficiency.
