Hi Jason,
Dr. Ning Wu has mathematically modeled Eugene Podkletnov discovery of weak gravitational shielding using quantum guage physics. In the below link Dr. Ning Wu discusses the mathematics involved, which is way over my head and area of study.
http://www.smvfp.com/gravity/0307225.pdfNASA, as well as other agencies, have taken Eugene Podkletnov discovery very seriously, but little information about testing the shielding of gravity effects of superconductor is available. If Eugene Podkletnov's discovery is proved to be valid, it could be the most revolutionary discovery of the last 500 year, which would profoundly effect life as we know it, and promisses a wonderful future.

It is interesting that shielding of electromagnet field has advanced to the point of practicality for shielding of particle radiation in travel to Mar, for example.
