The complex number field is an associative division algebra over the real number field. In this paper we define an inner product in this field, and take this new algebraic system as a tool to study a general combined electric-magnetic focussing-deflection system with superimposed fields The relativistic third-order geometrical aberration formulas for this combined system have been derived.
