Electrodynamic liftoff and propulsion with an array of plates spaced-apart ≈¼λ feed with RF in quadrature [0° 90° 180° 270°] ≈ [λ ¼λ ½λ ¾λ] for sequential FTL phase variation (f ≥ cL) → (L ≥ λ) in order to warp spacetime for generating thrust force in a more energy-efficient way than conventional expelling-mass rockets. Technologically feasible and implementable, for firstly enabling subluminal travels with advantage of being propellantless interacting with spacetime andor EM fields that permeate the universe.
