ABSTRACT:
An electromagnetic wave absorber includes a first electromagnetic wave absorbent member containing a magnetic loss material, and a second electromagnetic wave absorbent member containing a conducting material arranged in front of the first electromagnetic wave absorbent member. The second electromagnetic wave absorbent member has a shape including an aperture at a tip of a hollow cone.
