1. ### Complex Dielectric Permittivity

Ya, looking back i replaced \epsilon_0 with \epsilon ' (\omega) - j \epsilon '' (\omega) instead of k \epsilon_0. Thanks again!
2. ### Complex Dielectric Permittivity

Thanks. Wow. Turns out close. The way i done it was very dodgy though \frac{\pi k \epsilon '' (\omega) V^2}{d^2} Puttin in Ed for V: \pi k \epsilon '' (\omega) E^2 Broke down quite nicely as the end
3. ### Complex Dielectric Permittivity

Oh, rite! I was thinking it was an uncharacteristically simple question. I done that and got this: Z_c = \frac{d(\epsilon ''(\omega) - j\epsilon '(\omega))}{\omega kA(\epsilon ''(\omega)^2 + \epsilon '(\omega)^2)} Would the I use the absolute value of the imaginary part of that to get the...
4. ### Complex Dielectric Permittivity

Thanks for replying. Those websites r hard 2 make sense of but i didnt give it too long yet. Spent ages googling before i posted here and got nowhere though. It says dielectric permittivity becomes complex when an alternating signal is applied across it. I just assumed that they're talkin...
