Broadband radiation of small dielectric particles

A qualitatively new theoretical model of broadband ("white") thermal radiation of small dielectric particles is proposed. It is suggested and justified that the high intensity of this radiation may be due not to an extremely high temperature, but to the dielectric properties of the material and/or the dimensional effect of thermal radiation. The calculation of the radiation intensity of a blackbody and a spherical dielectric particle depending on the photon gas dimension is performed.
