Last Reviewed: (not done)

The Center for Electromagnetic Compatibility (CEMC) works with its industrial members to help solve problems related to unintentional electromagnetic effects. These unintentional electromagnetic effects, (including electromagnetic interference, signal/power integrity, and electromagnetic susceptibility) can seriously degrade the performance and reliability of electronic devices and systems and can affect safety, consumer satisfaction, manufacturing costs and processes, as well as regulatory compliance (both national and international).

Center Mission and Rationale

To develop analytical and experimental techniques for the solution of electromagnetic compatibility problems including electromagnetic interference, electromagnetic susceptibility, signal integrity, and power integrity.  To analyze the effectiveness application of EMC absorbing materials.  To develop techniques for analyzing the environmental affects on communications and data transmission due to the design of facilities such as hospitals and offices.

Special Activities

Facilities and Laboratory

The Missouri S & T EMC Laboratory experimental capabilities and facilities are recognized as state-of-the art and unique among universities and remain an important cornerstone in the success of the program.  Capital equipment is valued at approximately $3.5 million.  Previously located in the electrical and computer engineering building, the laboratory is currently located (since 2009) in the Hypoint Industrial Park, located a few miles off-campus.  This new facility (approximately 10,000 square feet) significantly increases both laboratory space and office space for both graduate students and staff.  Test facilities include an anechoic chamber (approximately 28 ft long by 20 ft wide by 18 ft high) in addition to a smaller shielded room.  The laboratory has network and spectrum analyzers up to 50 GHz, as well as non –commercial equipment developed by EMC lab personnel for near field scanning and ESD (electrostatic discharge) immunity. The EMC lab also has access to the machine shop located in the materials research center (on campus).

 

The University of Houston has laboratory space dedicated to electromagnetic research and simulation and has direct contact probing stations, a computing facility based on an 8 processor Sun Server with 32 G RAM and a 10 CPU cluster.
