Hello, I am wondering how one would go about calculating the radiant 
flux emitted from a topload.

I considered using Planck's hypothesis (E = hv) using Planck's 
constant and frequency, but i dont know if thats completely 
accurate?  I know that is for particle energy, but how would you go 
about calculating wave energy? (I know it should be same).  If 
radiant energy and wave energy is different (theoretically it 
shouldnt be..) then what would be the formula for radiant flux?  If 
there is another completely different method of calculating energy:
my coil-
secondary = 21mH
primary = 48uH
primary voltage = 8.4kV
resonant frequency = 259kHz

Thanks for all the help!
