Waveguide components have been widely explored for several decades, due to their inherent merits of low insertion losses, high quality (<;i>Q<;/i>) factors, and a significant power-handling capacity.

In this work, an electromagnetic black hole based on gradient-index metamaterials is designed and fabricated by drilling holes in easily available materials to achieve efficient microwave heating in ...

Researchers at the University of Illinois Urbana-Champaign are investigating phase-change as a way to improve heat-sinking in ...
