Biography

Marin Soljacic was born in Zagreb in 1974. After graduating from XV Gymnasium (MIOC) in Zagreb he got a scholarship from MIT where he got his BSc in physics and electrical engineering in 1996.[2] In 1998 he got his MSc from Princeton University and in 2000 he got his PhD in Physics. In 2005 he became a professor of Physics at MIT.[3] In 2008, he was awarded a MacArthur Fellowship.[4][5]

Work

In 2007 Marin Soljacic and his assistants successfully made the first efficient non-radiative power transfer at a distance of 2 meters turning on a 60 W light bulb. Energy transfer was 40% efficient. Professor Soljacic's experiments and work in wireless energy transfer are related in spirit to the work of Nikola Tesla in the early 20th century,[6] but also have significant differences: unlike Tesla's failed efforts at long-range wireless energy transfer, the Soljacic group focuses only on short-range transfer, and unlike Tesla coils which resonantly transfer power with electric fields (which couple strongly to surrounding matter, most famously inducing artificial lightning) the Soljacic proposal uses coupling primarily via magnetic fields.[6] This work is currently being pursued in Soljacic's WiTricity company. Soljacic believes that low-power commercial application of this technology, such as charging of mobile phones, is several years away.[7]

In addition to wireless energy transfer, Prof. Soljacic works on numerous problems on electromagnetism in materials structured on the scale of the wavelength, such as micro- and nano-structured materials for infrared and visible light, including nonlinear optical devices and surface plasmons. His recent research, supported by a US$20 million grant from the Department of Energy, focuses on use of photonic crystals in solar cells.[7]

Prof. Soljacic is an expert in photonic crystals and nonlinear optics. He has co-authored more than 60 scientific articles, is a co-inventor on 12 patents (10 more pending), and has given more than 40 invited talks at conferences and universities around the world. In 2005, he was awared Adolph Lomb Medal of the Optical Society of America, and in 2006, he was chosen by Technology Review to be one of the "TR35": top 35 innovators under the age of 35.

Wireless Power Transfer via Strongly Coupled Magnetic Resonances

"Using self-resonant coils in a strongly coupled regime, we experimentally demonstrated efficient nonradiative power transfer over distances up to 8 times the radius of the coils. We were able to transfer 60 watts with ~40% efficiency over distances in excess of 2 meters. We present a quantitative model describing the power transfer, which matches the experimental results to within 5%. We discuss the practical applicability of this system and suggest directions for further study."
