Dr. Graeme Dewar
Graeme Dewar received his Ph.D. from Simon Fraser University in 1980.
From 1977 to 1981 he was a lecturer at Princeton University and from 1981
to 1989 he was on the faculty of the University of Miami. In 1989 he
Dewar is currently involved with teaching the Physics 251/251L course,
an introductory physics course for science majors. He teaches the optics course
(Physics 325/325L) and several other courses as staffing issues dictate.
Dr. Dewar's research has centered on studying the radio frequency properties of magnetic materials. Much of this research is based on experiments performed on a sensitive microwave spectrometer, operating at 17~GHz, he built at UND. He is currently studying the magnetoelastic properties of Tefenol-D in the 12-18~Ghz range. He is also working on making negative index of refraction (left-handed) mesostructures with the aim of extending their operating frequency from the microwave regime to the far infrared.
