Measurement dielectric constant of new transformer oil at frequency 18 to 26 GHz (K Band): article / Nurul Elieya Che Muda
Abstract—Nondestructive, noncontact and real time evaluation of dielectric properties of low-loss liquids is important for applications such as service-aged transformer oil, biomedical, remote sensing and design of radar absorbing material. In this paper, present a method for measurement of dielectr...
