Private: Prof. Jamesina Simpson was awarded two grants from NASA
November 26, 2013
Prof. Jamesina Simpson was recently awarded two grants from NASA for one year totaling nearly $100,000. One grant is titled, “FDTD ionospheric mapping, and the other is titled, “Time-domain stochastic modeling of electromagnetic propagation in the ionosphere.” No equipment will be used, but I’ll be using the award to support two graduate students, Bach Nguyen and James Hirst.
Mostly my group’s modeling capabilities developed over the past decade, particularly our ability to account for more physics and geometrical details than previous approaches. For these two awards, we will be developing new models of electromagnetic wave propagation in the ionosphere. For the NASA EPSCoR grant entitled “Time-domain stochastic modeling of electromagnetic propagation in the ionosphere”, we will be developing a stochastic finite-difference time-domain (FDTD) model capable of calculating the confidence level that a communications or remote-sensing system will work. For the NASA grant entitled, “FDTD ionospheric mapping,” we will be modeling the communication link between a spacecraft and a ground station as the spacecraft is being launched into space. It is important to be able to maintain that communication link during take-off for communications, safety, and other reasons.
