ABSTRACT:
A two part waveguide consists of a fixed part formed of a metal sleeve provided with metal dividing walls and a movable part formed by a helix positioned within the sleeve and rotatable sleeve about an axis coaxial with the axis of the cylindrical sleeve. A plurality of magnetrons are positioned on the outer surface of the sleeve. The sleeve includes two openings, one for admitting material to be treated and the other for discharging the material to be treated. The openings are dimensioned so that the microwaves cannot leave the waveguide.
