Nonetheless, the coexistence of reinforcement and matrix phases with distinct thermal properties makes their ablation behavior highly complex. To clarify the mechanisms in different environmental conditions, femtosecond laser ablation experiments were performed in air and dynamic water. Herein, temperature evolution, groove profiles, surface morphology, and elemental composition were systematically analyzed. Results indicate that the dynamic water medium effectively suppresses local overheating of the SiC matrix, mitigating pit-like damage.

We first synthesized FeSiAl@SiC composites via ball milling, achieving a reflection loss of −57.12 dB and an effective absorption bandwidth of 6.24 GHz with a thickness of 3.22 mm. Subsequently, we employed a metastructure design (maintaining the overall structure thickness unchanged) for FeSiAl@SiC by replacing the partial absorber with a lossless medium layer containing resonant structures, where interfacial coherent cancellation was induced via electric resonance. This design basically retains the original absorption band while precisely enhancing Ku-band absorption at target frequencies, enabling the metamaterial absorber to achieve >80 % electromagnetic wave-absorbing across 5.6–15.61 GHz. It also improves the Radar Cross Section reduction performance at the complementary absorption frequency points.
