Silence for Waves: Inside INFRACHIP’s Anechoic Chamber
Inside of CROMA lies an anechoic chamber. Step inside, and the world goes silent, at least for electromagnetic waves. Every wall, floor, and ceiling is lined with pyramidal absorbers that prevent any reflection, while reinforced shielding transforms the room into a high-performance Faraday cage. The result: a perfectly isolated environment for the most sensitive wireless experiments.
“The goal is to reduce significantly all external interference and create free-space measurement conditions” explains Nicolas Corrao, the chamber’s lead engineer, which ensures users, from academic researchers to engineers, can quickly and efficiently run their tests.

Its flexible setup allows users to sweep antenna orientation in three dimensions and characterize signal behavior with great precision in a wide range of frequencies (between 800 MHz and 40 GHz). Scientist can thus test various types of antennas, depending on the size, the weight (up to 1.5 kg), the materials (plastics, textiles, bio-based), the type of radiation (directional or omnidirectional). A precious equipment for scientists who wish to design and test new kind of antennas, to analyse wireless device, or characterize advanced materials.

In keeping with INFRACHIP’s mission of openness and shared access, the CROMA’s anechoic chamber is available free of charge to the research community. With close technical support, Nicolas Corrao ensures that users are able to lead their experiments with a high level of autonomy, making it an attractive and easy-to-use tool as well for academics as for industrials.
While it is just one part of a much broader technological offering, the chamber embodies the spirit of INFRACHIP: enabling advanced research through accessible, well-supported facilities.
