Modelling the honeycomb composite for multilayer structural absorbing composite design

The honeycomb structure absorbing material, which has both load-bearing and absorbing functions, has an irreplaceable position in the field of modern absorbing materials. In order to realize the effective permittivity calculation of honeycomb absorbers for further multi-structure design. Here, firstly, the Maxwell-Garnett (MG) formula is derived to summarize the conditions of use and the scope of application. Secondly, a new effective medium model is constructed based on the MG formula and characteristics of honeycomb structured wave absorbing composites. Finally, Based on the MG formula, the equivalent calculation of an example using the model shows that the obtained permittivity is basically consistent with the measured permittivity, which proves that the model can predict the effective permittivity of the honeycomb absorbing composite precisely. This is of great guidance and use for the future design of multilayer honeycomb structures.
