Design of the nano / micro scale structure of nanostructured composites activable in the radio frequency/microwave range depending on the frequency of the electromagnetic field

For the prediction of electromagnetic performance by correlating the electromagnetic absorption properties with the structure, architecture and composition of nano-structured composites, simulations were performed for different combinations of substrate, inserts, mass density and particle size. CST software, designed for electromagnetic analysis and design in the high frequency domain, simplifies the process of creating the structure by using a solid graphical modeling that is based on the ACIS geometric modeling core. The article followed the influence of particle size by determining the variation of the relative total specific absorption rate by comparing the size of the inserts and the substrate used. At the same time, the influence of mass concentration on the variation of the relative total specific absorption rate was analyzed, respectively on the evolution of the ratio between the maximum specific absorption rate and the specific absorption rate.
