When β→90o, θ→0o, we see as the aura around a torch on the side of the light source,
If we pulse this emission (β→90o) at an appropriate energy density, ψ natural frequency, we have a shield that in the absence of a similar energy density field is attractive and in the presence of a similar energy density field repulsive.
This torch emits photons appropriate for the force needed. For example, photons carrying gravitational energy,
The frequency of ψ around these particles will be high given their size, but the source of this photons can be pulsed to produce an appropriate force field frequency.
But how to create a photon source that is the opposite of a laser; β→90o as oppose to β→0o?
