Abstract: A simple yet rigorous method has been developed to enable … Web31 okt. 2024 · The dielectric loss results from the inability of a polarization process in the material due to the applied electric field. Generally, the loss in a material is expressed in terms of the loss tangent. Thus, the loss tangent is used to calculate the dielectric loss ( {\varepsilon }^ {^ {\prime}}) of the nanocomposite materials using Eq. 2.
WebIn the ideal case, the losses are zero and the dielectric loss factor is zero. In the case of the capacitor mentioned above, the dielectric loss factor is given by the ratio of the charging current (90 ° out of phase to the applied voltage) to the loss current in phase with the applied voltage.
