Title: Method of changing characteristics of electric wave absorption material
Inventor: KOZUKA YOJI
IPC: H05K9/00
Filed: 2002-02-27
Abstract: <P>PROBLEM TO BE SOLVED: To effectively change matching characteristics and maintain constant characteristics of an electric wave absorption material by changing composition of the electric wave absorption materials.  <P>SOLUTION: The electric wave absorption material comprises a conductor, a dielectric and a magnetic material which are adhered, sprayed, coated, deposited, or printed partially on the surface the electric absorption material in an adjusted distribution ratio. Thus, matching characteristics of the electric wave absorption material are changed such that matching is available at a lower or higher frequency domain than that where matching was inherently available to an electromagnetic wave absorption material. Further, a conductor device mounted on the surface of the electric wave absorption material, in particular, is electrically coupled to a conductor board which is closely contacted with the back of the electric wave absorption material, or part of the conductor device is inserted into the electric wave absorption material, thereby substantially changing the matching characteristics such that matching is available at the lower frequency domain.  <P>COPYRIGHT: (C)2003,JPO
