A new method for determining the magnetic properties of solid materials employed in unconventional magnetic circuits (2017)
Journal Article

The mechanical and thermal properties of common, solid (non-laminated) ferromagnetic materials are widely available, but the electro-magnetic characteristics of such solid materials are often undefined. Existing characterization procedures such as th... Read More about A new method for determining the magnetic properties of solid materials employed in unconventional magnetic circuits.

Thermal Design of Linear Induction and Synchronous Motors for Electromagnetic Launch of Civil Aircraft (2017)
Journal Article

The engine size of modern passenger transport aircraft is principally determined by take-off conditions, since initial acceleration requires maximum engine power. An elec¬tromagnetic launch (EML) system could provide some or all of the energy require...
