Title: Electromagnetic wave absorption sheet and electromagnetic wave absorber element
Inventor: SHIMIZU KATSUAKI
IPC: H05K9/00
Filed: 1988-11-10
Abstract: PURPOSE:To obtain an electromagnetic wave absorption sheet having high electromagnetic wave absorption efficiency, a light weight and no absorption characteristic change by providing a conductive film continuously increasing in its area on an electrically insulating support, and three-dimensionally arranging the film. CONSTITUTION:An electromagnetic wave absorber element 1 is formed of a square columnar molding 11, and a conductive film 12 formed on the side faces. The film 12 is desirably continuously varied in its surface resistivity by continuously increasing its area, and exponentially varied in a direction (x). The characteristic impedance Z of the incident side end of radio wave is near that of the air, and the characteristic impedance of the opposite side end is desirably near that of the wall face. The film 12 is obtained by printing conductive ink on a support made of electrically insulating plastic sheet, etc. The film 12 is three-dimensionally arranged on the side faces of a rectangular parallelepiped. A distance l between the films is set to l<=lambda as compared with the wavelength lambda of the object radio wave. Thus, the element is formed by printing. Accordingly, a radio wave dark chamber can be constructed inexpensively and easily and is not affected by the influence of moisture.
