Electromagnetic waves in composites and polycrystals
In this chapter, the self-consistent methods are applied to the solution of the problem of electromagnetic wave propagation in the composites with spherical inclusions and polycrystals with quasispherical grains. For every method, the dispersion equation for the wave number of the mean wave field propagating in the composites is derived. The asymptotic solutions of these equations in the long and short-wave regions are obtained in closed analytical forms. Phase velocities and attenuation coefficients of the mean wave fields are calculated in wide regions of the parameters of the composites and frequencies of the incident waves. Predictions of various self-consistent methods are compared and analyzed.
