Marin Soljačić (born February 7, 1974) is a Croatian-American physicist and electrical engineer and Cecil and Ida Green Professor at physics department, MIT.

After graduating from XV Gymnasium (MIOC) in Zagreb he attended MIT, where he got his BSc in physics and electrical engineering in 1996.

In 2007 Marin Soljačić 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.

Professor Soljačić's experiments and work in wireless energy transfer are related in spirit to the work of Nikola Tesla in the early 20th century, [8] but also have significant differences: unlike Tesla's long-range wireless energy transfer in Colorado, the Soljačić 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 Soljačić proposal uses coupling primarily via magnetic fields.

In addition to wireless energy transfer, Prof. Soljačić works on numerous problems on electromagnetism [9] 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.
