Abstract
With the application of nanoparticles in the field of microwave absorption more and more widely, so it is of great practical value to apply them in large-scale space, and the research on the influencing factors of nanoparticles in large-scale space becomes the key. Considering the diversity of nanocomposites, MWCNTs and Fe3O4, which are easy to prepare, are selected to composite. First, MWCNTs/Fe3O4 nanocomposites are prepared by ball milling and characterized by XRD, TEM and network vector analyzer. Then, the electromagnetic parameters are equivalent by using the strong disturbance equivalent theory, and the absorption loss in the frequency range of 2–18 GHz is calculated by numerical simulation. Finally, the influence of the volume ratio of particles (fs), background medium (εb) and thickness of absorbing layer (d) on electromagnetic wave absorption loss in space is analyzed by orthogonal experiment, and the absorbing mechanism is analyzed.
