Modelling

@phaseshift has built a SketchUp model[14] (File:EM Thruster.skp) of a frustum based on the estimated Shawyer Flight Thruster dimensions.

@TheTraveller constructed an EMDrive Calculator spreadsheet to model thrust given various design parameters[15], which was built with some input from Roger Shawyer directly. See Useful EMDrive Design and Test Tools for more details.
