  The rapid development of chargeable devices has caused a great deal of
interest in efficient and stable wireless power transfer (WPT) solutions. Most
conventional WPT technologies exploit outdated electromagnetic field control
methods proposed in the 20th century, wherein some essential parameters are
sacrificed in favour of the other ones (efficiency vs. stability), making
available WPT systems far from the optimal ones. Over the last few years, the
development of novel approaches to electromagnetic field manipulation has
enabled many up-and-coming technologies holding great promises for advanced
WPT. Examples include coherent perfect absorption, exceptional points in
non-Hermitian systems, non-radiating states and anapoles, advanced artificial
materials and metastructures. This work overviews the recent achievements in
novel physical effects and materials for advanced WPT. We provide a consistent
analysis of existing technologies, their pros and cons, and attempt to envision
possible perspectives.
