Thanks Gary, this is quite relevant to what I have been talking about.
In my theory "gravity shielding" means creating a region of dark energy exotic vacuum with negative pressure by a variant on the Josephson effect using a real superconductor "impedance matched" to the vacuum.

Renormalizable Quantum Gauge General Relativity
Authors: Ning Wu
Comments: 138 pages, no figure
The quantum gauge general relativity is proposed in the framework of
gauge theory of gravity. It is formulated based on gauge principle which
states that the correct symmetry for gravitational interactions should be
gravitational gauge symmetry. The gravitational gauge group is studied in
the paper. Then gravitational gauge interactions of pure gravitational
field is studied. It is found that the field equation of gravitational
field is just the Einstein's field equation. After that, the gravitational
interactions of scalar field, Dirac field and vector fields are studied,
unifications of fundamental interactions are discussed. Path integral
quantization of the theory is studied in the paper. The quantum gauge
general relativity discussed in this paper is a perturbatively
renormalizable quantum gravity, which is one of the most important
of the quantum gauge general relativity proposed in this paper. A strict
proof on the renormalizability of the theory is also given in this paper.
Another important advantage of the quantum gauge general relativity is
it can explain both classical tests of gravity and quantum effects of
gravitational interactions, such as gravitational phase effects found in
experiments and gravitational shielding effects found in Podkletnov
experiments. For all classical effects of gravitational interactions, such
as classical tests of gravity and cosmological model, quantum gauge
relativity gives out the same theoretical predictions as that of the
Einstein's general relaitvity.
Gravitational Shielding Effects in Gauge Theory of Gravity
Authors: Ning Wu
Comments: 13 pages, no figure
In 1992, E.E.Podkletnov and R.Nieminen find that, under certain
ceramic superconductor with composite structure has revealed weak
properties against gravitational force. In classical Newton's theory of
gravity and even in Einstein's general theory of gravity, there are no
grounds of gravitational shielding effects. But in quantum gauge theory of
gravity, the gravitational shielding effects can be explained in a simple
and natural way. In quantum gauge theory of gravity, gravitational gauge
interactions of complex scalar field can be formulated based on gauge
principle. After spontaneous symmetry breaking, if the vacuum of the
scalar field is not stable and uniform, there will be a mass term of
gravitational gauge field. When gravitational gauge field propagates in
unstable vacuum of the complex scalar field, it will decays exponentially,
which is the nature of gravitational shielding effects. The mechanism of
gravitational shielding effects is studied in this paper, and some main
properties of gravitational shielding effects are discussed.
Key paper is T. W. B. Kibble's "Lorentz Invariance and the Gravitational Field" JMP 1961 reproduced in "Gauge Theories in the Twentieth Century" John C Taylor, Imperial College Press (2001), p. 119.
R. Utiyama Phys. Rev. 101, 1597 (1956) applied the local gauge force principle (e.g. Yang-Mills for weak and strong forces Phys. Rev 96, 191 (1954) anticipating modern QCD and standard U(1)SU(2)SU(3) model with 17 - 25 free parameters) not to the 4-parameter translation subgroup of the Poincare group, but to the 6-parameter Lorentz group of rigid space-time rotations. Kibble points out problems with Utiyama's approach and instead includes the 4-parameter translation subgroup, i.e. the entire Poincare group leaving out the 5 additional parameters (dilation and hyperbolic uniform acceleration) of the zero rest mass conformal group used by Roger Penrose in twistor theory.
Kibble finds that there is a small torsion field coupling only when Tuv(Matter) =/= 0 and that Einstein's
Ruv = 0
is obeyed in "vacuum". This was before the recent discovery of "dark energy" that Mike Turner says may well be w = pressure/energy density = -1 exotic vacuum with dominating negative pressure causing the Universe to accelerate its expansion rather than slowing down. This issue is still controversial due to recent NEWTON data as interpreted by some. It's too early to know.
Thanks to Waldyr Rodrigues Jr for reminding me about the NEWTON data crucial test of my model.
