8-5-1 - The Changing Landscape of Automotive Electronics Avram Bar-Cohen

Session Organizer: Dr. Przemyslaw Jakub Gromala, Dr. Ercan M. Dede Principal
Engineering Fellow
Dr. Avram Bar-Cohen is an internationally recognized leader in thermal science and technolo-
gy, an Honorary Member of ASME and Life Fellow of IEEE, currently serving as a Principal Raytheon- Space
Engineering Fellow at Raytheon Corporation – Space and Airborne Systems. His current efforts and Airborne
focus on embedded cooling, including on-chip thermoelectrics, diamond substrates, and Systems
two-phase microchannel coolers for high heat flux electronic and photonic components in
computational, radar, and directed energy systems.

Wireless Power Beaming - History, Applications, and Challenges

Although it was Nikola Tesla who conceived of microwave wireless power transmission more
than 100 years ago, it was W.C. “Bill” Brown of Raytheon who first reduced wireless power
beaming (WPB) to practice, with the 1965 invention of the rectifying antenna and the 1975
demonstration of 34 kW delivered at 2.4GHz across a one mile distance. Recent advances in
solid-state microwave technology have dramatically expanded the opportunity-space for WPB
and brought renewed attention to the system engineering, packaging, and thermal manage-
ment challenges that must be overcome if the full benefits of this disruptive technology are to
be realized.

WPB is a key enabling technology for powering space platforms, space exploration vehicles,
and future space colonies, as well as delivering solar power from space to the power grid on
earth and to remote off-grid locations. Such long-distance wireless power beaming, extending
well beyond conventional wireless power transmission (WPT), can also play a critical role in
delivering renewable power from uninhabited regions to the earth’s population centers and in
powering unmanned vehicles from ground-based or airborne transmitters.

This presentation will open with a review of Tesla’s and Brown’s pioneering work and continue
with discussion of the early and current WPB-based Solar Power Satellite efforts in the US,
Japan, and China, as well as other potential terrestrial and space applications. Attention will
then turn to describing a notional WPB system and the key component, packaging, and system
technologies needed to enable such applications, including compact solid state RF power
modules/converters, conformal and low mass RF receiver antennas, and advanced thermal man-
agement techniques. The presentation will close with a brief overview of the space solar power
roadmap recently presented to senior US government officials in the Defense, Diplomacy, and
Development Technology Innovation Challenge
