ABSTRACT:
A microwave launcher includes a hollow microwave cavity in the shape of a plus sign, four coplanar exit ports in the arms of the microwave cavity, and a non-coplanar entry port at a central hub of the microwave cavity. A single magnetron is in communication with the entry port. There is a controllable, electrically activated microwave barrier at each of the exit ports. Each microwave barrier includes an electrical signal input whose operation controls the activation of the microwave barrier. A switching circuit has a voltage source for the electrical signal input of each of the microwave barriers. Microwave power output from the single microwave source is launched from the selected exit port by using the switching circuit to selectively block microwave passage through each of the nonselected exit ports, but to leave the selected exit port unblocked.
