Ashwin Iyer explains how the new anechoic chamber works.
New equipment allows engineering researchers to conduct research in a room that looks like something out of science fiction. Thanks to some new equipment, researchers in the Department of Electrical and Computer Engineering are now able to conduct research on antennas in a setting that seems straight out of science fiction. The new anechoic chamber—part of Ashwin Iyer 's Near-Field Antenna and Metamaterial Characterization Facility—is a shielded room used to measure the direction and strength of signals transmitted by different antennas, and to characterize novel materials. "Prior to acquiring this chamber, we weren't doing any of this," said Iyer. "The university did not have any capacity to measure antennas like this." Aside from allowing new research activities, the chamber itself has a striking design. Almost every interior surface of the 16×12×11-foot chamber is covered with long, dense foam pyramids. These pyramids reflect and dissipate the signals that are being tested to avoid any echo.
