The formulas (1a & b) and their consequences below are my original discoveries today March 13, 2011 Pacific Time to which I and my estate retain all commercial/technology rights that may ensue.

Bottom line, for a thin spherical shell capacitor filled with appropriate meta-material of thickness d << Area A of concentric shells - the anomalous Newtonian g-force field just outside the outer electrically charged spherical shell should be of order of magnitude
g(anomalous repulsion) = c^2rs(applied EM field)/r^2
~  (index of refraction)^4G(-E^2d/c^2  (1a)
"(-" = negative meta-material permittivity
Therefore, without the "superconducting" index to the fourth power amplification we cannot hope to nullify g(Earth) ~ 10 meters/sec^2 with practical small amounts of applied electric field/voltage gradient between the inner and outer spherical shells filled with a properly designed meta-material.
Let V = voltage difference across the "plates"  http://en.wikipedia.org/wiki/Capacitor
C = Q/V
+ & - Q = charges on the plates
C = capacitance
V ~ Ed
~  (index of refraction)^4G(-V^2/dc^2
~  (index of refraction)^4G(-Q^2/C^2dc^2
Also from Maxwell's equations
index of refraction ~ (permittivity)^1/2   - for fixed permeability.

Therefore, the anomalous Newtonian gravity radial g-force field at the surface of the outer sphere is
~  (permittivity)^3(Newton's Gravity Constant)(Voltage Difference)^2/(distance between plates)(speed of light in vacuum)^2 (1b)
To get the right ELF resonance put a coil across the capacitor.
