Abstract

In this work, our study is based on the extraction of the complex effective permittivity, the complex effective permeability, and absorption of composites with the ferromagnetic wires in the X and Ku band. Three types of composites made of wire continuous grates and shortened CoFeNiBSiMo, CoFeSiB and CoFeBSiCr are considered to determine different spectra in the X and Ku band frequency. For this purpose, the Sij diffusion parameters were simulated using EM simulation software. Then, the calculated values were adjusted using the method of Nicholson Ross Weir (NRW) to estimate the values of complex relative permittivity and the complex relative permeability. The simulated values show a goodconvergence that guarantees the application of the used methodologies for the characterization of different composites. The results show that the nature of inclusions microwires exhibit significant effect on the complex permittivity and the complex permeability. The microwave absorbing properties of composites filled with glass-coated amorphous microwire are better and the frequency range of microwave absorption is controllable by adjusting the nature of inclusions molecular. All these results indicate the proposed composite are excellent candidate materials for the microwave sensing and structural interrogation applications. © 2016 by Nova Science Publishers, Inc.
