Dielectric crystal in the Planck blackbody [PDF]
arXiv, 2015 The dielectric crystal with the index of refraction n is inserted in the Planck blackbody. The spectral formula for photons in such dielectric medium is derived with the equation for the temperature of internal photons. The derived equation is solved for the constant index of refraction.

True Dielectric and Ideal Conductor in Theory of the Dielectric Function for Coulomb System [PDF]
, 2009 On the basis of the exact relations the general formula for the static dielectric permittivity e(q,0) for Coulomb system is found in the region of small wave vectors q. The obtained formuladescribes the dielectric function e(q,0) of the Coulomb system in both states in the "metallic" state and in the "dielectric" one.

Polarity-dependent dielectric torque in nematic liquid crystals
, 2008 The dielectric dispersion in the uniaxial nematic liquid crystals affects the switching dynamics of the director, as the dielectric torque is determined by not only the present values of the electric field and director but also by their past values.

The Theory of SERS on Dielectrics and Semiconductors [PDF]
arXiv, 2016 It is demonstrated that the reason of SERS on dielectric and semiconductor substrates is the enhancement of the electric field in the regions of the tops of the surface roughness with very small radius, or a very large curvature. The enhancement depends on the dielectric constant of the substrate and is stronger for a larger dielectric constant.
