Abstract:
1. A waveguide network for directing microwave energy from a microwave source to a microwave cavity, comprising: a first rectangular waveguide for receiving microwave energy from said microwave source, said first rectangular waveguide with an open input end, an open output end, and four sidewalls forming a rectangular cross section waveguide body, attached to an outlet side of a first flange, with said first flange attached to said microwave source, or additional connecting waveguide, with a second flange attached to said output end of said first rectangular waveguide, with the length of said first rectangular waveguide being half a wavelength times 1.25; a second rectangular waveguide attached to an outlet side of said second flange, with an open inlet end and an open outlet end, and four sidewalls forming a rectangular cross section waveguide body with the cross sectional rectangle waveguide body oriented at approximately 45 degrees to the angle of rectangular waveguide body of said first waveguide, with said outlet end of said second rectangular waveguide attached to an inlet side of a third flange, with the length of the second waveguide being selected so that two separate systems of fields are 90 degrees out of phase at an outlet end; with said second rectangular waveguide oriented to deflect a first portion of entering TE
