Demonstration of a Degenerate Band Edge in Periodically-Loaded Circular Waveguides


We demonstrate the existence of a special degeneracy condition, referred to as degenerate band edge (DBE), between 2 Bloch modes in periodically-loaded circular all-metallic waveguides at microwave frequencies. The DBE condition has been related to a dramatic reduction in cluster velocity and with some distinctive resonance properties, but it has not been shown in hollow waveguide structures nevertheless. Hence, we have a tendency to show here its existence in two periodic waveguide examples. The unit cell of the primary structure consists of a circular waveguide loaded with two inner cylinders with elliptical irises with misaligned angles. The second structure consists by loading the waveguide with elliptical rings. The demonstration of DBE in those waveguide is explained through a simple multi-transmission line approach where the conditions to get DBE are clarified, and suggests that the DBE can occur in many alternative analogous periodic waveguides. These structures can be probably used to investigate unconventional gain schemes in traveling wave tubes or different sorts of distributed amplifiers, oscillators and novel pulse compressors.
