Facilities


Facilities include offices on the third floor as well as a laboratory on the fourth floor of the Everitt Laboratory Building. The department has renovated the fourth floor to house the facilities for the Center for Computational Electromagnetics. On this floor, facilities are contained in 7600 sq ft of laboratory, office space, seminar room, computing laboratory, with an additional 200 sq ft for a machine shop. In addition, a four-processor SGI Power Challenge Array, SGI Extreme, two SGI Indigo, and four DEC Alpha workstations plus a number of personal computers have been purchased for the Center. The total cost of the new computing facility is over $300K. The University has contributed over $100K to the purchasing of computers and renovation of the laboratory. The laboratory has over 35 personal computers and workstations, and from which one can immediately access other computing facilities on the campus, which include the Convex Exemplar, Power Challenge Arrays, SUN-SPARC 2000, and MASS PAR. In addition, there is a completely enclosed microwave anechoic chamber. This chamber provides a 3-ft diameter spherical volume within which all reflected waves are at least 40 dB below the incident wave at operating frequencies as low as 700 MHz. A microwave receiver is currently used in the measurement of radiation patterns using the chamber. In addition, there is a small chamber which is used for impedance and S-parameter measurements. An HP8510 automated network analyzer is used for both types of measurements.

The Electromagnetics Laboratory also maintains two outdoor pattern ranges: One equipped with 30-ft towers and a maximum range of 70 ft, the second range consists of a 20-ft square ground plane equipped with a 15-ft fiberglass boom. It has a 36-in. diameter rotatable aperture plate at its center and provides for three degrees of freedom.
