Abstract:
1. A dual mode resonator for a pulse compression system comprising a conductive wall forming an enclosed resonator cavity, said resonator cavity being symmetrical about at least two orthogonal axes of the resonator, a first coupling port in the cavity wall for receiving pulse power from an rf pulse power source that excites a first mode in said cavity, said first coupling port being located at the intersection of the cavity wall with one of the resonator's axes, a second coupling port in said cavity wall for receiving pulse power from an rf pulse power source that is 90 degrees out of phase from the power received at said first coupling port, said second coupling port being located at an intersection of the cavity wall with a resonator axis that is 90 degrees from the axis for said first coupling port for exciting a second mode in said cavity which has a space and phase orthogonal relationship to said first mode, and at least two mode orienting perturbations in the conductive wall of said cavity at locations that fix the orthogonal orientation of the first and second modes excited in said resonator.
