Finite difference time domain modeling of subwavelength-structured anti-reflective coatings

Creator:: Han, Katherine, Han, Hai-Yue, Stack, James, Jr., and Chang, Chih-Hung
Abstract:: The finite difference time domain (FDTD) method was used to model anti-reflective properties of a variety of sub-wavelength structures for 300 to 1300 nm input light. Light hitting non-tapered nanostructures exhibited interference patterns similar to thin film anti-reflective coatings (ARCs), increasing the anti-reflective effect at several wavelengths. The lowest reflectance...

Molecular dynamics applications and techniques : a comparison study of silica potentials and techniques for accelerating computation

Creator:: Wolff, David
Abstract:: This thesis presents a study of applications and techniques for molecular dynamics simulations. Three studies are presented that are intended to improve our ability to simulate larger systems more realistically. A comparison study of two- and three-body potential models for liquid and amorphous Si0₂ is presented. The structural, vibrational, and...

Computational nanooptics in hyperbolic metamaterials and plasmonic structures

Creator:: Thongrattanasiri, Sukosin
Abstract:: This dissertation concerns several problems in the fields of light interaction with nanostructured media, metamaterials, and plasmonics. We present a technique capable of extending operational bandwidth of hyperbolic metamaterials based on interleaved highly-doped InGaAs and undoped AlInAs multilayer stacks. The experimental results confirm theoretical predictions, exhibiting broadband negative refraction response...

Monte Carlo Simulations of Structure and Melting Transition of Small Ag Clusters

Creator:: Collins, Lee
Abstract:: The behavior of small atomics cluster largely depends on their geometry, due to the high ratio of surface atoms to interior atoms. One interesting aspect to study clusters centers around characterizing the transition behavior between nite and bulk materials, where the ratio of surface atoms to interior atoms is very...

Finite-difference time-domain modeling of ultra-high frequency antennas on and inside the carbon fiber body of a solar-powered electric vehicle

Creator:: Han, Katherine, Freeman, Paul, Han, Hai-Yue, Hamar, Jacob, and Stack, James F., Jr.
Abstract:: Finite-difference time-domain simulations are performed on a 900 MHz band antenna inside and outside the carbon fiber body of a solar-powered electric vehicle. Data are analyzed to determine the optimal antenna placement for transmission to a receiving antenna located toward the rear of the solar vehicle. Modeling data are compared...

The construction and computational modeling of a fiber Bragg grating tunable laser diode

Creator:: Winz, Michele W.
Abstract:: The widespread adoption of wavelength division multiplexing to increase the bandwidth of optical fiber communication systems has provided a major impetus for research on low cost, single-mode, wavelength stable tunable diode lasers for use in optical telecommunications due to the large volume of lasers required. Other applications, such as demodulation...

Framework for Computational Modelling of Cellular Diffusion Systems

Creator:: Senger, Mitchell John
Abstract:: Many biological processes are regulated by the presence and movement of cellular Ca²⁺ ions. The concentration of Ca²⁺ in a cellular environment is regulated by IP₃ sensitive channels that lie on the surface of a cell’s endoplasmic reticulum. Little is known about the macroscopic effects of intracellular Ca²⁺ activity, so...

John Archibald Wheeler : a study of mentoring in modern physics

Creator:: Christensen, Terry M.
Abstract:: This dissertation has two objectives. The first objective is to determine where best to situate the study of mentoring (i.e. the 'making of scientists') on the landscape of the history of science and science studies. This task is accomplished by establishing mentoring studies as a link between the robust body...

Direct numerical simulation results for turbulent hydrogen/air flame: mixture-averaged diffusion model

Creator:: Fillo, Aaron J., Schlup, Jason, Beardsell, Guillaume, Blanquart, Guillaume, and Niemeyer, Kyle E.
Abstract:: This data contains results from direct numerical simulations of three-dimensional, premixed, hydrogen/air flames, using the mixture-averaged diffusion model. We performed the simulations using the finite-difference code NGA; simulation details are described completely in the associated article.

Connecting computational thinking and mathematics: an examination of linguistic opportunities and challenges

Creator:: Glickman, Abbie A.
Abstract:: In this paper, I used a linguistic lens of translanguaging and semiotics to examine how K-12 mathematics teacher candidates (TCs) create meaning around computer science (CS) and mathematics concepts in a computational thinking (CT) setting. I defined the term “disciplinary repertoire” as a mirror to the concept of a linguistic...
