4. HAWKINS - ARROWs ARROW stands for Anti-Resonant Reflective Optical Waveguide. These structures are unique because they allow for the guiding of light in waveguides with air or liquid cores. The purpose of this project is the fabrication and study of ARROW structures and the construction of photonic devices built using ARROWs. Project sponsored by NIH, NSF, and DARPA. Project relies on: Advanced Lithography Development, Metal and Dielectric Deposition, Chemical Etching of Core Materials, Research in Micro-fluidic Handling and Packaging, Scanning Electron Microscopy

5. HAWKINS – ION TRAPS Ion traps are the heart of a new family of mass spectrometers that are portable and low cost. We construct these ion traps using microfabrication to pattern metal electrodes on ceramic substrates and then tailoring the electric field across these electrodes with discrete capacitors on a matching PCB. Project sponsored by NASA. Project relies on: Advanced Lithography Development, Metal and Dielectric Deposition, Chemical Etching, PCB Design, Solder attachment and packaging

6. HAWKINS – SILICON DEVICES Solid-state Impact-ionization Multipliers This involves the production of silicon amplifiers based on impact ionization effects. These amplifiers are three electrode devices meant to be used with arbitrary current sources, especially photodiodes. Sponsored by NSF. Project relies on: Advanced Lithography, Metal and Dielectric Deposition, Silicon Processing, Electrical Testing, Understanding of silicon properties

7. SCHULTZ - Optical Fiber Devices • Fiber Grating Interrogator • Measure the wavelength spectrum of a fiber sensor • Use a tunable optical filter and a broad wavelength source • Make a ring laser for higher optical power • Fiber core replaced devices • Deposit active material into the core of an optical fiber • Create in-fiber device • In-fiber electric field sensor

8. Bangerter – magnetic Resonance imaging Improved B1 Mapping in the Presence of Noise This project seeks to improve the ability to create RF field maps for MRI in situations with very low inherent SNR. Partial Volume Correction for Sodium MRI Sodium MRI suffers from low SNR, leading to large image voxel sizes and partial-volume issues. This project seeks to improve the measurement of sodium concentrations with MRI by co-registering 23Na images with higher-resolution 1H scans. LAMA-SSFP: Simultaneous Fat Suppression and Band Reduction in MRI In this project, we are developing a new MRI method to suppress unwanted lipid signal while simultaneously reducing so-called “banding artifacts” in the images. All projects rely on advanced signal/statistical processing models, noise analysis, image acquisition modeling, image processing, and familiarity with MRI scanning techniques.

9. Mazzeo - DielectriC Spectroscopy Dielectric spectroscopy of liquid solutions probes the electrical properties of dispersed particles such as proteins. This approach is unique because it reveals the electrical structure of molecules and can track intermolecular interactions over time. Specifically, this research will be looking at electrical interactions in the formation of amyloid fibrils, which are implicated in disease. Project relies on: Thermal Stabilization, Electromagnetic Modeling, Instrument Control and Communication, Signal Processing, Liquid Handling and Measurement
