Electromagnetic Wave Absorption Properties of SiC/CoSi/CeSi Composites at Low Frequency and High Temperature

Caption

The ternary composite (SiC/CoSi/CeSi) achieves an impressive RL value of -66.48 dB at 3.65 GHz, while maintaining 94.5% of its absorption performance (-63.34 dB at 4.31 GHz) even after oxidation at 500 °C. We propose a transition metal-rare earth co-modification strategy, combining atomic-scale electronic structure regulation with microscale heterointerface engineering, effectively overcoming the bottleneck of low-frequency and high-temperature response of traditional SiC-based absorbers.
