Phys. Rev. ST Accel. Beams 9, 054401 (2006) [8 pages]Transverse impedance of axially symmetric tapered structures
B. Podobedov and S. Krinsky Received 4 April 2006; published 24 May 2006 We determine the low frequency transverse impedance of axially symmetric tapered structures. Higher-order perturbation theory is used to improve previous estimates due to Yokoya and Stupakov. For linear tapers, accurate numerical results are obtained using the abci electromagnetic simulation code. Based upon insight gained from the perturbation calculations, we introduce a simple parametrization that provides an excellent fit to all of our abci data—including cases with gradual and steep tapers as well as large and small change in cross section. ©2006 The American Physical Society
