  1. Lightning Electromagnetic Pulse Functions and Protecting the Artemis Spacecraft

    Roberts, Nathan S.University of Houston2024

    … waveforms measured near the Artemis spacecraft, and we demonstrate that our functions can meet standard “Component A” specifications more closely than contemporary standards. We work with transcendental equations to peak-correct or “normalize” these functions, then solve for parameters …

  7. A Higher -Order Finite Element: Boundary Integral Method for Electromagnetic Scattering and Radiation From Bodies of Revolution

    Dunn, Eric AlanUniversity of Illinois at Urbana-Champaign2015

    … is used to compute the radar cross section (RCS) and radiated fields of bodies of revolution (BOR). This is a 2.5-D problem since it allows simulations in a 2-D domain to correspond to a full 3-D object. The interior region, which corresponds to the local near-field of the scatterer/radiator is …

  10. Electronic and Optical Properties of Thin-Film Superconductors and Superconductor -Semiconductor Interfaces

    Roshchin, Igor VladimirovichUniversity of Illinois at Urbana-Champaign2015

    Application of an external ac field results in steps in the current-voltage characteristics at Vn = nho/2e. Experimental parameters of a highly-doped n+-InAs are used to obtain estimates for future experiments to be conducted to test the predictions of the model.
