Claim Text:
1. A high-power microwave RF window, comprising: a. a cylindrical waveguide, wherein said cylindrical waveguide comprises a ceramic disk concentrically housed in a central region of said cylindrical waveguide; b. a first rectangular waveguide, wherein said first rectangular waveguide is connected by a first elliptically-shaped joint to a proximal end of said cylindrical waveguide; and c. a second rectangular waveguide, wherein said second rectangular waveguide is connected by a second elliptically-shaped joint to a distal end of said cylindrical waveguide, wherein said elliptically-shaped joint spans from a flat surface of said rectangular waveguide to a wall of said cylindrical waveguide, wherein said elliptically-shaped joint is disposed to create a traveling wave inside said ceramic disk and disposed to minimize an electric field on a surface of said ceramic disk and disposed to minimize an electric field inside said ceramic disk.
