Dr. Raymond Rumpf, EMPossible’s lead instructor, was honored to be named to the Florida Tech Career Hall of Fame for 2020. Dr. Rumpf received his Bachelor’s and Masters’s degrees in Electrical Engineering from Florida Tech in 1995 and 1997 respectively, and his PhD in Optics from the University of Central Florida in 2006. Dr. Rumpf […]
Check out the visualization below – it can help explain why diffraction orders, or grating lobes, exist only at discrete angles. Waves that are reflected from (or transmitted through) a periodic structure take on the same period as the structure. The field must also be continuous. Only certain discrete angles allow the field to be […]
Dr. Raymond Rumpf recently travelled to Bangkok, Thailand to present a workshop on finite difference frequency domain (FDFD) to students at Bangkok University. Every student left with a working simulation of a diffraction grating.
Diffraction gratings are common optical elements in spectrometers, fan-out gratings, dichroic mirrors, and other filter devices. One common aspect of all of these is that they split an incoming wave into multiple diffraction orders. The direction of the diffraction orders depends on the angle of incidence and period of the grating relative to the wavelength. […]
Dr. Raymond C. Rumpf has been promoted to Fellow of the International Society for Optics and Photonics (SPIE), an educational nonprofit established to advance light-based science, engineering, and technology. Fellows are members of distinction who have made significant scientific and technical contributions in the multidisciplinary fields of optics, photonics, and imaging. They are honored for […]
