Abstract :
Synchronous wakefields in a dispersive waveguide are formulated in a general form. The fundamental role of group velocity in wakefield propagation, calculation of attenuation, amplitudes, form-factors and loss-factors is demonstrated for single-bunch and multi-bunch train. Waveguide adiabatic tapering and bunch density variations are taken into account analytically in the time-domain. Application of this approach to an oversized pipe with small corrugations and roughness is discussed
