Phys. Rev. D 42, 1819–1828 (1990)Wake fields in a dielectric-lined waveguideReceived 12 February 1990; revised 21 May 1990; published in the issue dated 1 September 1990 A cylindrical waveguide of radius a is filled partially with an isotropic dielectric between radii b<r<a. A particle travels along the guide, possibly with an offset from the axis, at a velocity v<c. The wake fields left behind are calculated. We find that the transverse wake forces do not vanish as γ-2=1-(v/c)2 or in any other way when v→c. The longitudinal and transverse wake forces are evaluated as a function of b/a. © 1990 The American Physical Society URL:
