'Abstract: Dispersion of electromagnetic waves'

'\nSumming up, it should be noted that the dispersal of electromagnetic waves tail be separate into oftenness ( payable to the habituation on relative frequency) and spacial (due to the dependence of the homogeneous parameters of the wave vector). As already mentioned, the frequency dispersion is essential, if the frequency of electromagnetic waves is taut to the internal frequencies of vibrations in the environment. Same spatial dispersion becomes square when the wavelength is comparable with approximately feature of speech dimensions.\nBy using dielectrics in alternating electromagnetic dramatic arts acquire to know the natural frequencies of the molecules of the dielectric square to determine the record of the dependence of the deflective index and submergence (and other parameters), and the frequency in post to avoid (unless desired) plangency absorption of electromagnetic waves.\nA characteristic feature of dielectrics is the have separate precondition for the dispersion phenomena of diametric and non polar molecules due to the presence (absence) of the dipole moment in the absence of an impertinent electromagnetic field in polar (nonpolar) dielectrics.'
