A system, method and computer program product are provided for reducing a deactivation function utilizing an optimal reduction. The invention also relates to an aperture matched polyrod antenna which includes the same and an inductive tuning element used to achieve wideband impedance match and to create a Gaussian beam in the radiating near field of the antenna, suitable to mimic a small region plane wave. The film is provided on one side with a PVDC or acrylate coating so that it can be used as roll-wrap packaging. The first configuration permits substantially unrestricted fluid flow between the first and second ports. One or more race reliefs extend into the first raceway andor the second raceway.
