Claim:
1. A T-junction microwave applicator comprising: a rectangular main waveguide of uniform width comprising a first arm and a second arm extending in opposite directions along a main axis from a central junction to distal end walls, each end wall having a port; a conveyor disposed to convey material to be heated along the main waveguide entering through one of the ports and exiting out the other port; a junction arm extending perpendicularly from the main waveguide at the junction through which electromagnetic energy is supplied to the main waveguide, wherein the junction arm forms a three-arm T junction with the first and second arms of the main waveguide; wherein the main waveguide includes a conductive ridge disposed opposite the junction arm and extending in length through and past the junction along the lengths of the first and second arms of the main waveguide between the end walls to achieve uniform heating across the width of the main waveguide along its length.
