Permittivity of metal
WebJul 15, 2024 · 1. With the addition of polymer and metal ions, increasing frequency caused a slight decrease in the measured real permittivity and a significant decrease in the effective permittivity at frequencies ranging from 0.2 GHz to the inception of polymer-interactive, or metal-interactive, resonance polarization. WebA metal can be considered as an ionic lattice embedded inside an electron sea. The periodic ion lattice causes a periodic potential, which is very hard to calculate. Therefore, we often …
