Another photon model is one in which energy is emitted along a line by reflection off the high density front of an accelerating field, over the rear focus and out the back low density portion of the field. At each node of the oscillation the symmetry of the photon is changed as in the 'camera obscura'. Such a 'photon' will remain linearly localized by oscillating at right angles through the line of motion.
The 'photon' I am postulating here is analogous to the drop of water that is ejected upward when a pebble is dropped into still water (concomitantly with a plane localized wave spreading outward on the surface).
Note: There are only 5 types of images (XCLNT) which can go through a camera obscura. Of these, the 'N-form' represents a handed rotation. Such a rotation is given a half-twist (180 degrees) at every node but always retains the same handedness.
If such a photon exists it must be unpolarizable. That is, an experiment designed to detect individual photons will be unaffected by the relative positions of two polarizers insinuated between the emitter and detector. A 'rectifying' lense may be needed to correct for 'spreading' in a plane perpendicular to the grain of the polarizer. With such a rectifyer in place, any orientation of the two polarizers must produce the identical expectation of detection.
The planar wave photon diminishes as 1/r away from its source whereas a group of linear photons will spread out as 1/r^2 (like bullets).
