The optical properties of multi-scale plasmonic structures and their applications in optical characterization and imaging

Creator:: Kuhta, Nicholas Anthony
Abstract:: The optical response of metallic structures is dominated by the dynamics of their free electron plasma. Plasmonics, the area of optics specializing in the electromagnetic behavior of heterogeneous structures with metallic inclusions, is undergoing rapid development, fueled in part by recent progress in experimental fabrication techniques and novel theoretical approaches....

Subwavelength light confinement and quantum chaos in micro- and nano-structured metamaterials

Creator:: Govyadinov, Alexander A.
Abstract:: This dissertation concerns a broad range of unique phenomena related to the light propagation at nano- and micro-scales. To access the nano-domain, we introduce anisotropy-based waveguides with positive- and negative-index modes. These novel structures allow energy propagation in subwavelength regions and, in contrast to surface waves, have the mode structure...

Electromagnetic properties of anisotropic plasmonic metamaterials

Creator:: Elser, Justin Lee
Abstract:: In this dissertation we study the electromagnetic properties of plasmonic metamaterials. We develop an analytical description to solve the fundamental problem of free-space scattering in planar plasmonic systems by utilizing anisotropic metamaterials. We show with exact numerical simulations that these manufactured materials do completely eliminate the scattering, and even in...

Sub-diffraction light propagation and imaging in planar negative refraction waveguides

Creator:: Wangberg, Robyn
Abstract:: In this dissertation we study the electromagnetic properties of planar waveguides with non-magnetic strongly anisotropic dielectric cores. We develop an analytical description of the mode propagation in these systems and show that the index of refraction can be either positive or negative depending on the specific material parameters. Propagating modes...

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...

Trends in Emergency Medical Service Activations for Suicide Attempts in Adolescents Before and After the Start of the COVID-19 Pandemic: An AutoRegressive Integrated Moving Average (ARIMA) Time-Series Analysis

Creator:: Johnson, Kelly M.
Abstract:: The coronavirus pandemic and its associated public health response resulted in disruptions in daily life as well as financial and other insecurities. This corresponded with an increase in adverse mental health outcomes in adolescents in the United States, including a temporary increase in suicidal ideation and behaviors. The pandemic also...

Health Service Utilization among Medicaid Enrollees in Oregon : Assessing Variation by Level of Rurality

Creator:: Larson, Annie E.
Abstract:: Research Objective: Nearly 60 million people in the United States reside in a rural area. Residents in rural areas have higher rates of chronic disease, risky health behaviors, disability, infant mortality, and age-adjusted mortality than their urban counterparts. Health insurance and access to care mitigate those risks, in part because...

The Association Between Patient Activation and Cost, Utilization, and Outcomes Among Patients Undergoing Elective, Primary Total Knee Arthroplasty

Creator:: Owen, Erin Callahan
Abstract:: Background. Total knee arthroplasty, or replacement, is a common, generally successful, and expensive procedure. Tools to predict outcomes following orthopedic procedures are abundant, yet no commonly used assessment accounts for an individual’s propensity to engage in adaptive health behavior. The 13-item Patient Activation Measure (PAM) questionnaire is a tool that...

Examining Hypertension Prevalence and Health Behavior Practices of Sub-Saharan African Immigrants in the United States

Creator:: Nikuze, Scholastique
Abstract:: African-born population is one of the fastest growing group in the United States. Very little is known about their socio-demographic characteristics, health behavior practices and long-term health. The purpose of this study was to examine hypertension prevalence, health behavior practices and the impact socio-demographic factors have on these outcomes among...

Predictors of participation in a prison-based parenting program

Creator:: Schumer, Jean Ellen
Abstract:: The focus of this study was threefold. This research examined the extent to which parenting alliance between incarcerated parents and the caregivers of their children, influences participation of inmate parents in parenting programs. This research explored the extent to which family contact influences participation of inmate parents in parenting programs....
