Abstract
With the ever-deepening understanding of nano-electromagnetic interactions and the advancements of fabrication
methodologies of nanomaterials, diverse electromagnetic platforms utilizing nanomaterials have been developed
for next-generation electromagnetic safeguarding applications. This study presents the design and fabrication of
bioinspired porous Ti CT /Si N composites featuring an aligned lamellar structure, aimed at facilitating the

effective absorption and dissipation of electromagnetic radiation. The layered configuration of Ti CT /Si N

composites facilitates the repeated reflection of electromagnetic waves between neighboring Ti CT layers, hence

enhancing the energy dissipation of these waves. At a Ti CT concentration of merely 0.21 wt.%, the effective

Ti CT /Si N composites demonstrate advantages in lightweight characteristics and robust mechanical properties,
