Foundational Paper on How to Model a Really Complicated Multi-Loop/Coil Inductive System

Theoretical Modeling of Complicated Inductive Wireless Power Transfer Systems
Scott Roman, Gregory D. Durgin
2020 IEEE International Conference on RFID (RFID)

Inductive RF power transfer designs can be incredibly versatile, designed with a multiplicity of geometries and current paths to focus and enhance the transfer of power. However, most inductive systems in engineering practice are limited to either two-flat-loop systems or several basic coils with simplifying symmetry aspects. Complicated loop designs are largely ignored or untried by engineers because they are notoriously difficult to understand and model. This paper presents a foundational model for inductive systems with an arbitrarily large number of mutually-coupling loops. For the first time, comprehensive first-principle expressions for calculating voltage gain, s-parameters, and transfer efficiencies for these arbitrarily complicated inductive systems are presented and compared to measurements. The final result is a set of tools for designing the next-generation inductive RFID and wireless power transfer systems.

IEEE RFID 2021 Hybrid Conference in Phoenix, 27-29 April 2021

Posted on Written by

Next year’s annual installment of the IEEE RFID 2021 will be a hybrid conference in Phoenix, AZ from 27-29 April 2021.  Planned to be co-located with RFID Journal LIVE!, the conference will allow both presenters and attendees to join either in person or online.  Open calls are on the website for papers, workshops, and tutorials.  Hopefully we will all be able to meet in person in 2021!

 

What Should Gen3 Be?

Posted on Written by

“What Should Gen3 Be?” was the provocative title of the online panel session run last month as part of IEEE RFID 2020.  This was one of the more fascinating panel sessions I’ve seen in recent years. Organized by Prof. Mohammad Alhassoun from KFUPM (GTPG alum), the panel of industry and academic experts led to some lively perspective about the current and future of RFID.  Youtube link below for those that would like to revisit the panel in its entirety.

 

Congratulations, Erik Centeno

Congratulations to GTPG member Erik Centeno! He was awarded the 2020 ECE Opportunity Research Scholars (ORS) Outstanding Service Award for the academic year.  Erik has been a tireless member of ORS for four years, serving on our very own Space Solar Power team.  He has graduated this spring from Georgia Tech and will be joining AT&T in Atlanta.  Well done, Erik!
