Jeffrey N. Vinik Associate Professor of Electrical & Computer Engineering (2007 - 2012)
Professor Cummer’s research explores the interaction of electromagnetic fields with complicated structures and environments. In Professor Cummer’s other primary research, his group engineers materials that have electromagnetic properties that are not easily obtained or controlled in natural materials. His group has developed experimental techniques to probe these engineered materials and it was the among the first to demonstrate that the materials can have the unusual properties predicted theoretically. Using these techniques along with computer simulations, Professor Cummer’s group contributed to the design of a material that can smoothly bend radio waves around an object, rendering it effectively invisible.
