The dielectric constant and loss factor of the core samples of the Tipam group form Lakhomoni oil field was studied at different Both dielectric constant and loss factor have shown frequency dependence. While dielectric constant was observed to decrease with frequency, the Loss factor showed more ...
We treat permittivity as a complex function of the angular frequency of the applied field ɛ(ω). For the generalized refractive index and dielectric constant: ɛω=ɛ′ω+iɛ″ω By using complex numbers for the dielectric constant, we can specify the magnitude and phase. The values ...
In electrical engineering and electronics, the dielectric losses are characterized by the loss tangent: tanδ. However, the most general physical characteristic of losses, particularly for description of frequency dependences, is the complex dielectric constant: ɛ∗ω=ɛ′ω−ɛ″ω,tanδ=...
