Abstract
An electromagnetic wave absorber is provided with a first dielectric material layer (90, 200, 220) having two surfaces, a wave reflection layer (91, 201, 221) laminated on the one surface of the first dielectric material layer, a first resistive layer (92, 202, 222) laminated on the other, opposite, surface of the first dielectric material layer (90, 200, 220), and a second dielectric material layer (95, 205, 225) disposed proximate to the first resistive layer (92, 202, 222) leaving an air space, (94, 204, 224) having a thickness sufficient to determine adjust absorption characteristics for polarized waves, between the second dielectric material layer and the first resistive layer.
