Self-magnetically insulated power flow

Electromagnetic power transport through self-magnetically insulated vacuum transmission lines has been developed into a useful and reliable technology. A power density of 160 TW/m2 has been transported at approx. 100 percent efficiency over six meters. The theoretical understanding of power flow through lines of constant cross section has progressed through analytical theory and 2-D electromagnetic particle simulations. However, work needs to be done on the effects of line transitions in which the cross section changes in the direction of power flow. The major features of our present understanding will be reviewed and some promising hypotheses now under investigation will be presented
