Targeting the application demands in civil electromagnetic pollution protection and performance improvement of military combat equipment, our research group adopts the magnetoelectric collaborative design strategy to develop magnetoelectric composite microwave absorbing materials featuring thin thickness, light weight, broad absorption bandwidth and strong absorption capacity. This work addresses the inherent limitations of single-component absorbing materials, such as monotonous loss mechanisms and restricted performance.
Focusing on the compounding technology of magnetic and dielectric dual components, we systematically optimize preparation routes including core-shell structure fabrication and heterogeneous doping, and establish precise regulation methods for heterogeneous interfaces. The electromagnetic wave loss performance is effectively enhanced via interfacial coupling and synergistic effects. We also introduce a data-driven research paradigm and construct a theoretical correlation model linking microscopic morphology, electromagnetic parameters and microwave absorption performance. Combined with advanced characterization techniques such as high-resolution electron microscopy and in-situ electromagnetic measurement, the microscopic loss mechanisms of microwave absorption are revealed at the atomic scale.
Based on the fundamental theoretical achievements, we further promote the engineering development of microwave absorbing devices. By incorporating the optimized magnetoelectric composite absorbing fillers into polymer and inorganic matrices, a series of products have been developed, including flexible absorbing films, high-temperature resistant structural absorbing plates, low-frequency dedicated absorbing coatings and modular anechoic chamber absorbing components. A full-process performance regulation framework covering molecular structure design, controllable powder preparation and mass production of molded devices has been established. A variety of magnetoelectric composite microwave absorbing materials with the advantages of thinness, light weight, wide bandwidth and strong absorption have been successfully fabricated. The relevant research outcomes provide crucial theoretical support and technical references for the domestic industrialization of high-performance absorbing materials applied to stealth protection and electromagnetic interference suppression.
