Flux Displacement in Rectangular Iron Sheets and Geometry
... Hysteresis loss for one loop is independent of the speed of magnetization and therefore, it is assumed to be only linearly dependent of the frequency, whereas eddy-current loss is squarely proportional to frequency. The results presented in section C, however suggest a different behavior. Flux is di ...

Input Impedance, VSWR and Return Loss of a Conformal Microstrip
... The antenna is experimentally tested and the author compared the result with the software results. It was founded that the resonance frequency of the conformal antenna is shifted toward higher frequencies compared to the flat one. The effect of curvature on a fringing field and on the resonance freq ...

Dielectric
A dielectric material (dielectric for short) is an electrical insulator that can be polarized by an applied electric field. When a dielectric is placed in an electric field, electric charges do not flow through the material as they do in a conductor, but only slightly shift from their average equilibrium positions causing dielectric polarization. Because of dielectric polarization, positive charges are displaced toward the field and negative charges shift in the opposite direction. This creates an internal electric field that reduces the overall field within the dielectric itself. If a dielectric is composed of weakly bonded molecules, those molecules not only become polarized, but also reorient so that their symmetry axes align to the field.The study of dielectric properties concerns storage and dissipation of electric and magnetic energy in materials. Dielectrics are important for explaining various phenomena in electronics, optics, and solid-state physics.
