Resonant Inductive Coupling Wireless Power Transfer (RIC-WPT) is a leading field of research due to the growing number of applications that can benefit from this technology: from biomedical implants to consumer electronics, fractionated spacecraft and electric vehicles amongst others. However, current applications are limited to symetric point-to-point-links. New challenges and applications of RIC-WPT emphasize the necessity to explore, predict and optimize the behavior of these links for different configurations: multi-point RIC-WPT networks and assymetrical systems. In this work a design methodology oriented towards the optimization of assymetric RIC-WPT links is presented, resulting in a closed analytical formulation of the optimal frequency at which an assymetrical RIC-WPT link should operate. Finally, the resulting efficiency-optimized link si explored and compared to previous results obtained in RIC-WPT symetric configurations [1, 2].
