The idea is to manipulate the phase difference between the fields at two radiating slots of the antenna to reform the beam. Metal vias are introduced to create two coupled half-mode cavities in the patch antenna. The mutual coupling between the two cavities makes the phase difference as a function of the operating frequency. The simulated beam scans …

Chemical and Biochemical Engineering Faculty Research & Creative Works

Electro spun poly-l-lactic acid (PLLA) fiber scaffolds are used to direct axonal extension in neural engineering models. We aimed to improve the efficacy of these fibers in promoting neurite outgrowth by altering surface topography and reducing fiber elastic modulus through the incorporation of a compatibilized blend, poly-l-lactic acid-poly(pentadecalactone) (PLLA-PPDL) into the solution prior to electrospinning. PLLA+PLLA-PPDL fibers had a larger diameter, increased surface nano topography, and lower glass transition temperature than PLLA fibers but had similar mechanical properties. Increases in neurite outgrowth on PLLA+PLLA-PPDL fibers were observed, potentially due to the significantly increased diameter and surface coverage with nano topography. …
