#PhysicsFactlet
If you put a dipole close to a mirror it is easy to see that its emission pattern is modified due to interference. A bit less easy to see (and thus less known) is the fact that also the total emitted power depends on the distance from the mirror, as at certain distances a significant fraction of the reflected wave goes back on the dipole in antiphase with the emission, thus reducing the emitted power.
