Claim 17:
18. An apparatus for thermally treating a flowable material, the apparatus comprising:
a waveguide defined by first and second arms that extend in opposing directions, wherein each arm comprises a termination end that includes a reflector plate and a port for allowing a conduit to pass therethrough;
a conduit for receiving a flowable material, wherein the conduit passes through the first and second arms and wherein at least a portion of the conduit is transparent to electromagnetic energy;
a multi-port applicator junction that delivers electromagnetic energy to the first and second arms of the waveguide; and
a generator for providing electromagnetic energy to the multi-port applicator junction through an input port;
wherein each waveguide arm includes an output that is isolated from the output of the other arm and optionally includes a phase shift, such that any reflected electromagnetic energy exits the arm through an exit port different from the input port.
