The Attempt at a Solution

I'm fairly certain I'm not making correct use of the information given about the radiated power in order to solve this problem.

It is also possible that I've made mistakes elsewhere as well.

What am I doing wrong?

Those are working. But the one with your writing on is a little difficult to read.

Anyway, about the problem, you start off with the equation for the magnetic flux through the area of the coil, which is good, this does cause the emf. But then you start using the notation Hyi I'm not sure what this means. From the context, it looks like it should be the magnetic field, right?

And then you give the radiated power as the real part of the square of the electric field, divided by something that looks like the symbol nu. What is the symbol meant to represent?
