On the Topological Robustness of Vortex Modes at Microwave Frequencies

Vortex fields carrying orbital angular momentum are robust with respect to a wide range of external disturbances and exhibit self-healing properties. These peculiar characteristics have been deeply investigated at optical frequencies but only a few of them have been observed at microwaves. In this p...
