Transfer Matrix Approach to Propagation <strong>of</strong> Angular Plane Wave Spectra Through<br />
Metamaterial Multilayer Structures<br />
Presenter(s): Han Li<br />

Electro-Optics Graduate Program - Graduate Research<br />
The development <strong>of</strong> electromagnetic metamaterials for perfect lensing and optical cloaking has given rise to novel multilayer bandgap structures<br />
using stacks <strong>of</strong> positive and negative index materials. Gaussian beam propagation through such structures has been analyzed using transfer<br />
matrix method (TMM) with paraxial approximation, and unidirectional and bidirectional beam propagation methods (BPMs). In this thesis, TMM<br />
is used to analyze non-paraxial propagation <strong>of</strong> transverse electric (TE) and transverse magnetic (TM) angular plane wave spectra in 1 transverse<br />
dimension through a stack containing layers <strong>of</strong> positive and negative index materials. The TMM calculations are exact, less computationally demanding<br />
than finite element methods, and naturally incorporate bidirectional propagation.<br />
Design, Prototyping and Evaluation <strong>of</strong> an Elastically-Based Mechanical Starter for<br />
Automotive Engines<br />

This thesis presents the design and prototyping <strong>of</strong> a torsion spring-driven mechanical starter for potential use in vehicle engines. Torsion springs<br />
are considered for this application for three primary reasons. First, a charged spring can deliver the brief but powerful burst <strong>of</strong> energy required<br />
during starting. Second, once the starting energy is stored in a mechanical state, as in a spring, conversion losses are eliminated like those present<br />
with the traditional battery to electric motor to engine arrangement. Third, these springs can be inexpensively charged by a motor and<br />
battery significantly smaller than those currently in use, thereby reducing the negative environmental impact associated with the disposal <strong>of</strong><br />
those components. The realized design combines fundamental machine components into a new starter concept, a bench top prototype <strong>of</strong> which<br />
was assembled for validation. Experiments and an accompanying analysis <strong>of</strong> the starter proved useful for sizing the device for commercial implementation,<br />
as well as identifying additional design concerns for a more roadworthy prototype. This work is part <strong>of</strong> a larger effort on developing<br />
mechanisms that use elastic elements to harvest, store, and power devices useful in automotive applications.<br />
Music and its Affect on Learning and Studying<br />
Presenter(s): Jessica L Morell<br />
Advisor(s): Michael J Kozak<br />
Engineering Technology - Independent Research<br />
Music is a part <strong>of</strong> our everyday lives and can affect us in many different ways. Music can have a great affect on the learning process. I have written<br />
a paper and have done a study that examines how listening to music can affect the learning and studying process. I did a study with fifty college<br />
students with different backgrounds, majors, study habits, ages, and genders. The study tests many <strong>of</strong> the different factors that are involved with<br />
how music can affect learning. The paper I have written includes all <strong>of</strong> my results and all <strong>of</strong> the research I have done about how music affects the<br />
learning and studying process.<br />
A Pilot Study <strong>of</strong> the Effect <strong>of</strong> an Acute Vestibular Therapy on Postural Stability, Gait<br />
Variability, and Gaze Patterns <strong>of</strong> Children with ASD<br />

Children with Autism Spectrum Disorder (ASD) struggle with sensory regulation, resulting in decreased motor control, unusual gaze patterns,<br />
and decreased postural stability. Sensory integration therapy is a common therapy used to help children with ASD with these issues, however,<br />
there is insufficient quantitative research concerning the actual results <strong>of</strong> sensory integration therapy with respect to human biomechanics. It is<br />
