Professor Emeritus Arthur R. McGurn, CPhys, FInstP, is a Fellow of the Institute of Physics, a Fellow of the American Physical Society, a Fellow of the Optical Society of America, a Fellow of the Electromagnetics Academy, and an Outstanding Referee for the journals of the American Physical Society. He received a Ph.D. in Physics in 1975 from the University of California, Santa Barbara, followed by postdoctoral studies at Temple University, Michigan State University, and George Washington University (NASA Langley Research Center). The continuing research interests of Prof. McGurn have included works in the theory of: magnetism in disorder materials; electron conductivity; the properties of phonons; ferroelectrics and their nonlinear dynamics; Anderson localization; amorphous materials; the scattering of light from disordered media and rough surfaces; the properties of speckle correlations of light; quantum optics; nonlinear optics; the dynamical properties of nonlinear systems; photonic crystals; and meta-materials. He has over 150 publications spread amongst these various topics. Since 1981 he has taught physics for 38 years at Western Michigan University where he is currently a Professor Emeritus of Physics and a WMU Distinguished Faculty Scholar. A number of Ph.D. students have graduated from Western Michigan University under his supervision. He has previously published two books: Nonlinear Optics of Photonic Crystals and Meta-Materials (2015) and Nanophotonics (2018).
