Dr. Michael E. Gehm
In this talk, I will provide an overview of several of the active research areas in my lab at the University of Arizona. My primary area of interest is computational sensing¿a sensor design approach that jointly optimizes the physical and computational aspects of the sensor and, in so doing, achieves performance beyond that of traditional designs. In particular, my efforts focus on adaptive computational sensors and practical compressive sensing architectures; I will discuss simulation and experimental results in both areas. Computational sensing requires the ability to control or encode the physical field of interest. In the optical domain, a powerful approach is to impose this encoding over a propagation volume. This potential application sparked my interest in the second research area that I will discuss¿additive manufacturing for fabrication of arbitrary electromagnetic materials. In this section of the talk I will discuss our first steps toward creating such materials and provide some insight into the path ahead.
