use of either dielectric or magnetic properties in terms of its adjustable material as absorber for electromagnetic waves

摘要

In a process for manufacturing a material having predetermined dielectric, pyroelectric and/or magnetic properties use is made of the fact that the electrical properties of mesoscopic particles (approximately 1 nm to 100 nm), for example of metallic or semiconductor materials incorporated in a support matrix, such as ceramics or plastics, vary in function of the particle size. The material so obtained is used in particular to manufacture electrotechnical components, in particular for use in high-frequency and microelectronics applications.
