Approaching Q-Factor Bounds by Combining TM and TE Modes on a Cylindrical Shell
Original language description
Surface current densities on cylindrical shells are studied in terms of fundamental bounds on Q-factor. It is shown that the optimal current solution is not feasible by means any of practical realization. A solution with the second lowest Q-factor is found using the resonant composition of modes. This current solution is proved to be attainable as a cylindrical helix. Optimal modal composition is studied with respect to cylinder eccentricity and diameter to length ratio. It is shown that a circular cylinder yields a Q-factor close to fundamental bounds, however, the limiting case of a rectangular plate yields only a Q-factor associated with the TM bound. The physical reasons for this behaviour are explained.
