So, to understand the importance of the certain physical parameters (spectral width, specific pulsation and the number of particle) on the dielectric properties of the dense media, one varied these parameters to observe their influence on the real and imaginary susceptibility as well as the indication of the environment. Besides knowing that the Drude model is a particular case of the Lorentz model, a comparative investigation has been done to observe their behavior according to certain parameters. Keywords: Dielectric, Susceptibilities, Permittivity, Refractive Index, Pulsation, Width Spectral, Particles 1. Introduction The investigation of the physical properties in the dielectric and ferroelectric materials carries a particular interest at the researchers because of their applications in the field of the electronics and optoelectronic. Several authors have already worked in this domain with diverse applications such as in the field of the energy, electronics, optics etc. One knows that a material is dielectric if it does not contain electrical charges susceptible to move in a macroscopic way. Thus the environment cannot lead the electric current and by definition is an electrical insulator [1] such as the space, the glass, the dry wood, the plastics, etc. [2]. The dielectric are not however inert electrically. Indeed, the constituents of the material can present to the atomic scale of the electrostatic dipoles, which interact with an applied external field. This interaction is translated by the creation of a polarization P connected with the microscopic level in this electric field by the polarizability and in the macroscopic level by the electric susceptibility χ [2]. The dielectric materials [3-10] are classically likened to isolation materials. Insulators are materials of which the resistivity is extremely raised. They are characterized by an important width of the forbidden band (4eV) the kinetic energy due to the thermal motion is consequently insufficient. Insulators are essentially materials with Ionic connections, in which the electrons of connection are strongly localized. There are several types of dielectric; however electric cables are often protected from a plastic cover to avoid the exit of the electric current. Now a day, one puts dielectric materials [6] having a strong dielectric constant between the armatures of the condenser to increase their efficiencies. These materials belong to the ferroelectrics family, in particular the products from the titanate of Barium BaTiO 3 , which are used in the industry of the microelectronics for more than 50 years. One also notes ceramic, ancestrally used, knew new applications in the domains of the high technology, they play an important role in the technological challenges thrown to the industry. Most of the dielectric is also transparent in wide frequency bands, and are sometimes used to constitute one anti-reflection, for example on certain models of glasses. The dielectric [7] being difficult to ionize, the ambient air becomes a driver before them, that’s why one can use them for high-voltage condensers. 2.
