Is low power fast warp drive to the stars and beyond possible?

Now what we really want in the metamaterial for practical low power warp drive is not propagating radiation, but very low frequency off-mass-shell propagating near fields, which we may be able to get from the aforementioned strong EM field nonlinearities. Ideally, for example, we want the Fourier transforms of the material responses for the electric permittivity alone that is strongly negative for low frequencies as close to static as possible. I imagine such a longitudinally polarized non-propagating quasi-static near electric field in a properly designed hypothetical meta-material containing a Bose-Einstein condensate sandwiched between two parallel oppositely charged conducting plates – a new kind of electrical capacitor where
