BPERM version 3.0—A 2D wakepotential/impedance code

Therese Barts, Weiren Chou
BPERM 3.0 is an improved version of a previous release (1). The main purpose of this version is to make it more user friendly. Following a simple l-2-3 procedure, one obtains both text and graphical output of the wakepotential and impedance for a given geometry. The calculation is based on a boundary perturbation method (2-5), which is significantly faster than numerical simulations. It is accurate when the discontinuities are small. In particular, it works well for tapered structures.
