Abstract
Recent advances in additive manufacturing have significantly expanded the design
and fabrication capabilities of carbon fiber-reinforced polymer (CFRP) structures,
particularly in the context of electromagnetic microwave absorption (EMWA).
This review provides a comprehensive overview of the current state of research
