Homework Statement
We have the setup shown in the figure (see http://cl.ly/JGDDfigure). It rotates with angular velocity ω counter clockwise. ¿Power radiated by the system? (Sorry if it's not the correct translation -- Potencia radiada in spanish).
Homework Equations
[itex]P_{rad}=\frac{μω^{4}p^{2}}{12πc}[/itex]
The Attempt at a Solution
The dipoles 1 and 2 can be written (module) as p=lq=√2q. Can be split in its x and y components:
Dipole 1
p_x = √2q cos (ωt + 45)
p_y = √2q sin (ωt + 45)
Dipole 2
p_x = √2q cos (ωt - 45)
p_y = √2q sin (ωt - 45)
Dipole 3 (given)
p_y = p sin (ωt + 90)
Now, since they do not interfiere between them (orthogonal), we can write
[itex]p^{2} = p^{2}_{x} + p^{2}_{y}[/itex]
in the equation for P.
Is this correct? Thanks!
