From the post "High Frequency EMW From Laser" dated 31 Jul 2015 and "It's All Fluorescence Outside, Inside" dated 29 Jul 2015, the cone provides the asymmetry that differentiate between a counter clockwise rotating particle generating a \(E\) field outwards and a clockwise rotating particle generating a \(E\) field inwards. This asymmetry is lost when \(\small{\theta\to90^o}\),
Both clockwise and anti-clockwise rotations generate a \(E\) field parallel to \(PO\). This radiation is distinct from EMW and photons. Neither,
\(B=i\cfrac{\partial\,E}{\partial x}\)
nor
\(B=-i\cfrac{\partial\,E}{\partial x}\)
is applicable. And occurs in a single burst as \(\small{v_{cir}\approx0}\) is swapped as \(\small{v_{shm}}\) on emission and the particle stopped oscillating, from the post "It's All Fluorescence Outside, Inside" dated 29 Jul 2015.
This is a short burst of \(E\) field towards \(O\).
