A manifold is constructed with a primary manifold section to which the input wave guides are connected and a tuning section attached to the output of the primary manifold section. The tuning section is constructed of a deformable material which allows the dimpling of the internal wall to alter the impedance of the waveguide system for the purpose of fine tuning the impedance matching of the manifold.

Why it's free to use
- Filed May 4, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended May 4, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 4, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
