Demonstration of Electromagnetic Formation Flight and Wireless Power Transfer
Allison K. Porter,Dustin J. Alinger,Raymond J. Sedwick,John Merk,Roedolph A. Opperman,Alexander Buck,Gregory Eslinger,Peter H. Fisher,David Miller,Elisenda Bou +9 more
TL;DR: The Resonant Inductive Near-Field Generation System (RINF) as discussed by the authors uses a single set of hardware to perform both electromagnetic formation flight and wireless power transfer operations in a six-degree-of-freedom microgravity environment.
