Here, composites filled with carbon nanospheres of different morphologies exhibit the same electromagnetic wave (EMW) absorption and loss mechanisms when they possess content. Conductive is their primary EMW absorbing mechanism, while effect polarization can be ignored entirely. Composites a filling amount lower than percolation threshold certain conductivity excellent behavior, close to or higher reveal outstanding EM interference (EMI) shielding. The minimum reflection (RLmin) maximum...
Abstract Microwave absorbing materials have been becoming a countermeasure and security media for radio environment, also the main military force attached by world. In this study, experimental data, theoretical researches FEKO—a 3D structure electromagnetic field analysis simulation tool, namely, FEldberechnung bei Korpern mit beliebiger Oberflache, are effectively combined. Through systematic studies on parameters microwave properties of high-performance functional particle Fe 3 O 4 -rGO...
Whether conductive loss depending on conductivity or polarization related to defect degrees, total pore volumes, and specific surface areas determines electromagnetic wave (EMW) resisting performance needs be clearly explained. Meanwhile, materials with frequency-selective EMW absorption both high-performance absorbing shielding performances are currently research hotspots. Here, composites filled carbon spheres of different morphologies exhibit the same mechanisms when possessing content....
