Radio wave absorber

Abstract

The purpose of this invention is to achieve high absorption performance in a wide frequency band without increasing the number of layers or the thickness of each layer. The electromagnetic wave absorber (1) of this invention has a magnetic layer (2) with a self-resonant frequency in the millimeter wave band and a reflective layer (3). The magnetic layer (2) is provided with a plurality of plate-shaped monoliths (4) containing non-metallic magnetic materials, and the plate-shaped monoliths (4) are separated from each other by linear gaps (5a, 5b).
