1 Simpson, Jamesina J.Efficient modeling of impulsive ELF antipodal propagation about the earth sphere using an optimized two-dimensional geodesic FDTD gridThis letter reports the initial application of a geodesic finite-difference time-domain (FDTD) grid to model impulsive extremely low frequency electromagnetic wave propagation about the Earth sphere. The two-dimensional transverse-magnetic grid is comprised entirely of hexagonal cells, except for a ...2004-01-01
2 Ziegenfuss, DonnaA Busy Professor's Guide to Sanely Flipping Your ClassroomThe Flipped Classroom has become a popular teaching method. Students watch video lectures before class, saving class time for active learning (problem solving, demonstrations, applications, etc.). This paper is a useful guide for busy professors who would like to try out the flipped classroom approa...flipped classroom; inverted classroom; engineering education; teaching electromagnetics; assessment pedagogy2019
3 Simpson, Jamesina J.A review of progress in FDTD Maxwell's equations modeling of impulsive subionospheric propagation below 300 kHzWave propagation at the bottom of the electromagnetic spectrum (below300 kHz) in the Earth-ionosphere waveguide system has been an interesting and important area of investigation for the last four decades. Such wave propagation is characterized by complex phenomena involving nonhomogeneous and aniso...2007-01-01
