Major advances in the development of electric vehicles (EV) – buses, cars, high speed trains, etc. – have
been made using a new wireless power transfer technology named the “Shaped Magnetic Field in
Resonance” (SMFIR) that can send electric power over a significant distance. SMFIR is a basic technology
that can be used in many applications where electric power has to be supplied remotely without using
conductive wires. The “On-Line Electric Vehicle” (OLEV) is a SMFIR-based electric vehicle, which was
chosen as one of the 50 Best Inventions of 2010 by the TIME magazine. In this paper, the underlying design
for SMFIR is presented, which was done applying the Independence Axiom of Axiomatic Design Theory.
