Metaphasic shielding is a form of shield technology invented by Dr. Reyga, a Ferengi scientist, in 2369.


It is capable of withstanding the pressure, radiation and energy of a star's corona.

  • The technology was installed on the shuttlecraft "Justman," but Reyga was murdered shortly before the shields were proven.
    • The prototype systems included the metaphasic projection matrix, an EPS flow regulator, a polarized field emitter coil and a radial force compensator.
    • The shield was vulnerable to a phased ionic pulse beamed directly into the projection matrix. This resulted in a temporary system malfunction, a disruption of the metaphasic shield, during which a tetryon field would form inside the ship.

Subsequently, Dr Beverly Crusher successfully demonstrated the shield's effectiveness by piloting the Justman into the corona of a star.


Lieutenant Commander Geordi La Forge then developed the technology further, for exclusive use on the USS Enterprise-D in 2370.

  • La Forge's version of these shields involved a steady increase of the subspace compression factor of the shields, which corresponded in the decrease of the field distortion from 4,562 to 4,513 millicochranes, after which the metaphasic field was engaged.


When the USS Voyager explored the Delta Quadrant, a prison facility was found to employ metaphasic shielding.

  • It was discovered that the prison's shields suffered from periodic energy fluctuations, and Voyager was able to penetrate the shields using radion beams.
    Transporter beams could then be carried by the radion beam, thus allowing transporters through the shields.
