Our staff has the expertise and dedication to provide quality turnkey anechoic chamber facilities for EMC and high frequency applications. Along with the different types of chambers that we offer, we can put together complete measurement systems to include instrumentation and software. In order to provide most accurate design possible and ensure guaranteed performance, Cuming-Lehman Chambers has developed computer modeling software to prototype our EMC Chambers. Our "proprietary" Three Dimensional- Finite Difference, Time Domain (3D-FDTD) modeling approach actually solves the electromagnetic fields inside the chamber, thereby providing us a tool to determine the best combination of chamber size and absorber configuration. With fifty years of construction experience, our company has built a solid reputation of completing our projects on time and within budget. Since our parent company was established as a general construction firm, we’’re also capable of building host building structures to house our anechoic chambers. Our past project references demonstrate the quality of our workmanship and the vast experience we’’ve gained over the years. Our design/build approach ensures that our chambers meet the specifications the first time, on time and without expensive modifications or retrofits.
