FINE COMPOSITE STRUCTURE MAGNETIC SUBSTANCE ABSORBING GHz BAND RADIO WAVE AND RADIO WAVE ABSORBING MATERIAL |
摘要 |
<P>PROBLEM TO BE SOLVED: To provide a magnetic substance absorbing electromagnetic wave exhibiting high absorption performance and a wideband specification for a region from several GHz to several tens GHz in order to reduce an electromagnetic interference and health troubles in the frequency band of GHz. <P>SOLUTION: Fine composite structure magnetic substance powder for a GHz band radio wave absorber where fine particles of a magnetic substance principally comprising a metal or an alloy of Fe or Co or a compound of B or N are combined uniformly with fine particles of a rare earth oxide is produced using a melt quenching method. It is then mixed with resin or the like to manufacture a radio wave absorber in the form of a sheet, a board or a cube. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
