| DESCRIPTION:
These animations illustrate electric dipole radiation
from a point electric dipole. The dipole moment vector
is always vertical, and its magnitude varies sinusoidally
with an amplitude of 10%. In the first animation, we
show the fields in the quasi-static zone, the induction
zone, and the radiation zone. The motions of the field
lines are in the direction of the local Poynting flux
vector.
In the second animation, we show selected fieldlines
in the quasi-static zone near the dipole itself.
In the third animation, we show a selected fieldlines
that cross the quasi-static zone into the radiation zone.
