An Impedance Boundary Condition for Computing Beam Coupling Impedances
in Complex-Shaped Perforated Beam Pipes

June 1998
Abstract:
An equivalent wall impedance is introduced to describe
the electromagnetic boundary conditions at
perforated walls, which together with
general perturbational formulae
can be used to provide accurate analytical estimates
of longitudinal and transverse
beam coupling impedances
in complex-shaped partially perforated pipes.
Keywords: impedance RF-structure
