Homework Statement
It's me again:)
I have an antenna which emit the electrica power with the formula P given at the relevant equations. Now I shall calculate the impendance which the current generator "recognizes" which feeds the antenna with the current.
Homework Equations
[tex] P=\frac{p_{0}^{2}*\omega^{4}}{12\pi\epsilon*c^{3}} [/tex]and [tex] p(t)= p_{0} *sin(\omega*t) [/tex]
I know that P isn't given this way normally, but the task says it this way.
The Attempt at a Solution
My attempt is that I thought the power which is given by the generator must be same which is emitted by the antenna, so p is constant, in order to find the impendance. My problem is I'm not sure which formula I need for the power from the generator. The generator must use alternating current, mustn't it?
Thanks for help in advance
