Beam-fanning novelty filter with enhanced dynamic phase resolution.


We demonstrate a novel method to enhance the phase resolution of a barium titanate beam-fanning novelty filter by means of an external phase shift in one part of the signal wave. The new technique is described theoretically on the basis of the coupled-wave theory. Experimental results are presented to demonstrate the behavior and the advantages of the novel… (More)
