Abstract

PURPOSE:To obtain an electric wave absorber having an excellent oblique incident property, by using a plural number of layers in which the content of the conductive particle increases successively and at the same time forming the cross section of the final layer into a triangle using the arriving direction of the electric wave for the apex. CONSTITUTION:The electric wave absorber is formed by connecting the unit blocks A in a desired number. The block A is composed of layers 1-4, and the content of the conductive particle is minimum in the layer 1 that serves as the projection face of the electric wave and then increases successively toward the layers 2 and 3 to be maximum at the layer 4. The layer 1 is composed of a plural number of elements 1a having a cross section of an equilateral triangle, and the layer 2 is formed with a rectangular cross section. The layer 4 has a cross section of an equilateral triangle with its vertical angle touching the rear face of the layer 2. And the base opposite to the vertical angle is distributed nearly in parallel to the base of the element 1a. With such distribution of the layer 4, the layer 3 having a triangular cross section is provided in the space between the layers 4 and 2. In such constitution, an excellent obliquie incident property can be obtained.
