Laboratory Facilities

Electromagnetics Laboratory (EML)

The EML at the University of Colorado Colorado Springs supports undergraduate and graduate laboratory courses and research activities. Undergraduate and graduate laboratory courses have been developed in the areas of microwave, millimeter-wave, and infrared (IR) diagnostic techniques to support the existing courses in electromagnetic theory. Significant research activity is being devoted to RF/Microwave systems, high power microwave and millimeter-wave vacuum electronics, microwave and millimeter-wave solid state technology, microwave integrated circuits, antenna and phased array, and terahertz electronics. The EML features an anechoic chamber and a microwave measurement facility. It possesses high power ac service and a chilled water recirculation system, thereby permitting high average power experiments.

 

The 27’x22’x12’ broadband, shielded anechoic chamber is capable of antenna testing and pre-compliance EMC/EMI measurements. An anechoic chamber is a shielded room designed to attenuate sound or electromagnetic energy. It is filled with special cone shaped absorber that is designed to absorb echoes caused by internal reflections of a room and to provide a shielded environment for radio frequency (RF) and microwaves. The performance for emission testing, Normalized Site Attenuation (NSA) is approximately ±10 – 15 dB between the 30 – 200 MHz and ±4 dB from 200 MHz and above. Measurement is fully automated using NI’s Labview program.
