The Electromagnetic Waves Scattering Evaluation on the Composite Material Fractal Structure with Radioisotope Elements

The studies results of the electromagnetic waves reflection and scattering incident on the composite materials surface with radioisotope inclusions (CMRI), which are materials with irregular and non-stationary homogeneity, are presented. It is proposed to describe the radioisotope elements used to create non equilibrium states of the semiconductor matrix electronic subsystem, a model in which the conductivity distribution along one coordinate is a fractal function with a complex structure. The representing CMRI source possibility as the secondary radiation in the fractal phased model of a antenna array (FMAA) is shown. The influence of the secondary emitters non-stationary structure, which are a-particles tracks, on secondary radiation is estimated. The CMRI non-stationary structure is taken into account in the FMAA model in the elementary emitters coherence violation form, which is accompanied by a variation in the material's conductivity fractal dimension. The relations (ratios) are given for evaluating the electromagnetic waves (EMW) secondary radiation from the CMRI. Numerical estimates of the electromagnetic waves scattering and reflection from the CMRI are performed. The reflected signal reducing possibility level in the emitter direction due to the only in homogeneous material structure is shown to be no less than a magnitude order (excluding absorption).
