The approach taken here is to proceed from a relatively simple model to a more complex description, examining each one in turn. The first model relates to the computer calculations of Maffei, in which electrons of constant energy are reflected by cusp mirror magnetic fields on the faces of a truncated cube, but no electric field is present. The analytic model invoked here for this system analyzes a single face cusp of a truncated cube configuration as representative of the complete polyhedral pattern. Electron reflection coefficients, losses and other features and characteristics of this single-face model are found to give good agreement with the results of the Monte Carlo calculation conditions for low loss rates are indicated. These analyses are all limited to single particle behavior, the basic cusp mirror reflection mode of electron confinement.
