Abstract :
The wireless power transfer (WPT) efficiency of systems based on strongly coupled magnetic resonance (SCMR) depends on the Q-factor of the system elements, which is a function of the geometrical parameters. This letter analytically derives the equations that can be used to design optimal loop and helical elements for SCMR systems. Also, for loops and helices, a global maximum condition is derived in order to design SCMR systems with maximal efficiency.
