Now..the problem with field integration is the inevitable issue of solids and their lattice structures. In this context, field integration means the point at which the solid and the field 'integrate' with one another. the actual fundamental point at which they meet, in our mundane analysis. In optics, all the action happens right at the surface. In electrical terms, all the action happens right at the surface.
Optical distortion has a direct formulaic comparison to electrical distortions. In electrical terms, we call it 'impedance' (skin effect). Which is a form (and origin) of phase distortions which are connected to the issue of this integration. (sort of, long story)
You have to create a field, a coherent field, around the ship or vehicle. yet, you've got a distortion issue. The only way around that is to create a solid which behaves like a coherent field, so the field can be projected coherently. so the two can be stable with respect to one another.
There are a few ways to achieve this. one is the brute force and ignorance method of vortex technology. Then shield the given cavity with fleshy bits in it... the human whatever capsule, from the fields.. but the capsule still within the fields, so the effect is mitigated and the capsule moves with the distorting field, or differential field.
The next step is to shape the solid, in the same form as the desired field. Then, to gate the solid, electronically, at very high static voltage levels, so the field is created, and static, controllable, directable.
Part of the secondary method is tied to the above few posts. Go back another post or two and you will see the mentioning of two solar panels and their planar fields which have a FTL aspect in the longitudinal domain. This is tied to this secondary methodology. But, yet..the trick is to get the 'gating-tuned-solid'...to be the formation of the distortion field. To surpass glass in an alloy, that is like..in essence..fused silica (fiber optic) lensing. So that the casimir forces of differential from atom to atom, that work so well in the spinning vortex, are embodied in the alloy. Oh, gosh, the tri-state metals above, just happen to be...wires, kinda like fused fiber optic lensing. hhmm....(not really a terribly good engineering solution, but it is testable, an experimental potential, it is)
At least that is a secondary method of doing things. There are others.
