Terahertz time-domain spectroscopy is used to research the intermolecular or intramolecular interactions and some optical properties, such as refractive index, dielectric constant and absorption coefficient. As the dopant in terahertz band, non-absorbing particles, such as polyethylene...
The structure of the electric double layer has long been described by the classical Poisson-Boltzmann (PB) theory, in which a uniform dielectric coefficient is often assumed. Experimental data and molecular simulations evidence that the effective dielectric coefficient decreases with local ionic ...
The evaluation of the transmittance, reflectance, refraction index, extinction coefficient, real and imaginary parts of dielectric constant as function of wavelength illustrates that the optical response of nanocomposite thin film (ZnO)0.5–(Co3O4)0.5depends on the influence of two mediums of pure ...
