Printed Electromagnetic Structures and the All-Dielectric Revolution
Keywords: Printed, Dielectric, Electromagnetic
The EM Lab in the W. M. Keck Center for 3D Innovation at the University of Texas at El Paso is developing technology that will enable electromagnetic devices to be "printed" using a variety of additive manufacturing (AM) techniques. The team is developing materials, processes, and new device concepts that fully exploit the benefits of AM. The effort is focusing on all-dielectric electromagnetics to form devices more capable of operating at high power, provide lower loss, more easily embedded, make systems more difficult to reverse engineer, and for retrofitting electromagnetic devices with minimal compatibility issues. Electromagnetic waves interact very strongly with metals enabling compact and high performance devices to be produced. All-dielectric electromagnetic devices can only compete with their metallic counterparts through clever engineering of their dispersion and anisotropy. This leads to devices that are highly volumetrically complex making them impractical to fabricate by any means other than additive manufacturing.
