SUMMARY
The discussion centers on the analysis of dipole antennas and their relationship with electromagnetic waves. Participants confirm the use of relevant equations, specifically addressing the equality of electric and magnetic energy densities. A critical point raised involves the incorrect value of the permittivity of free space (ε₀), indicating a significant error in calculations. This highlights the importance of accurate constants in electromagnetic theory.

I think you are using the right equations as far as I've read. The electric energy density is equal to the magnetic energy density, etc. But isn't your value for ##\epsilon_0## way off? You've got completely the wrong exponent.
