 Lewis Little's Theory of Elementary Waves
If the waves meet when both are at their crest the resultant wave of their combination is larger than the sum of the originals.
So the ghost-like packets of waves in the standard theory have been replaced by a real existent, and the behavior of that wave is contrary to standard interpretation - the wave moves in reverse, from the target, or more generally from the detector, towards the source.
The wave itself is moving from the detector to the source; no dynamic information propagates through the wave; the wave carries the information as it moves.

 Back Action Paper
The recombination of the waves from both slits exerts a quantum force on the particle whose effects exactly reproduce the observed statistical coherent wave patterns for ensembles of particles whose initial positions are postulated to obey the Born probability rule.
These nonlinearities in the Schrodinger equation which are generically induced in mean-field approximations to many-particle effects are swept away by second-quantizing the wavefunction so that it is now a creation and destruction operator of elementary excitations of collective modes in non-relativistic solid state physics.
If we accept the postulate that the quantum wave is "pre-mind", then the direct affect of the particles of matter on their attached wave is a change in that wave that is an internal representation or map of the material environment in the sense of models of artificial intelligence.

 Quantum Mechanics 1
When Born showed that the solution of Schrodinger's wave equation could be interpreted as a non-observable object used only as an intermediary to calculate relative probabilities of the various allowed outcomes of an experiment, and when Bohr and Heisenberg solidified this interpretation (the so-called "Copenhagen interpretation") Schrödinger objected strongly.
Whatever the correct wave equation might be, it should contain the relations between wave and particle properties that seem to apply for particles (or waves) moving freely through space.
Solutions of the wave equation in the e-m case are the E and B fields of the wave.

Schrodinger was an unconventional man. Throughout his life he traveled with walking-boots and rucksack and for this he had to face some difficulty in gaining entrance to the Solvay Conference for Nobel laureates.
Schrodinger’s wave equation was the second theoretical explanation for the movement of electrons in an atom, the first being Werner Heisenberg’s matrix mechanics.

The equation says that the second derivative of Y with respect to x is equal to a function of x and Y.
In the Schrodinger equation, the curvature is proportional to the magnitude of the function, so Y(x) flattens out as it approaches the axis, and for an appropriate value of E the approach to the axis will be asymptotic.

It arises from an analysis of the purely radial component of the Schrodinger wave equation of the ground state, which is spherically symmetrical and has an angular quantum number of zero.
The superiority of the wave mechanical model of the hydrogen atom over Bohr's model is immense, because it not only duplicates and (in a sense) "explains" the quantized energy levels, it actually gives the complete probability density functions for the various possible stationary states.
