A major challenge for many critical defense and commercial applications is finding material solutions capable of surviving extreme environmental conditions, such as high shock, high power and high temperatures while maintaining desirable electromagnetic and mechanical properties. This is particularly challenges for electromagnetic applications such as antenna integration or electromagnetic sensing where conventional materials cannot survive the extreme environmental conditions. Ceramics offers one material solution but is often difficult to form into complex three-dimensional geometries. A promising solution is offered by the rapidly growing field of additive manufacturing (AM). In this presentation we will present some of our experience with ceramic AM, using the XJET Nano material jetting technology. In this presentation we will present the wideband electromagnetic properties of the printed ceramics from 1 GHz – 500 GHz.  We will also present several practical examples of printed electromagnetic ceramic devices including high temperature radomes and wide bandgap photonic crystals.

Learning Objectives:

  • Understand the basics of ceramic AM and its application towards electromagnetic devices
  • Understand the wideband electromagnetic properties of ceramic devices printed using the nanojetting technology
  • Understand how ceramic AM fabricated devices would survive in extreme environments
