With the rapid advancement of information technology, electromagnetic radiation has become deeply integrated into nearly every aspect of modern life, from personal communication and industrial manufacturing to aerospace and national defense infrastructures. As the electromagnetic environment has become increasingly complex and congested, electromagnetic waves have not only brought unprecedented convenience but also introduced serious challenges, including electromagnetic interference, radiation pollution, and information insecurity. Consequently, the rational design and development of microwave absorption materials (MAMs) are critically important for protecting human health, mitigating electromagnetic pollution, and strengthening information security in the information age.
