Dielectric materials are greatly desired for electromagnetic absorption applications. Lots of research shows that conduction loss and polarization are two of the most important factors determining complex permittivity. However, the detailed dissipation mechanisms for the improved microwave absorption performance are often based on semiempirical rules, lacking practical data relationships between conduction...
Nowadays, low‐frequency electromagnetic interference (<2.0 GHz) remains a key core issue that plagues the effective attenuation performance of conventional absorption devices prepared via the component‐morphology method (Strategy I). According to theoretical calculations, one fundamental solution is to develop a material that possesses a high ε′ but lower ε″. Thus, it is attempted to control the...
