MIMO Wireless Power Transfer for Mobile Devices

We have developed novel strategies for exploiting multiple-input and multiple-output (MIMO) channels for wireless power transfer (WPT). Through the use of backscatter channel measurement, the channel state information for each mobile device can be rapidly acquired at minimal energy cost. We have demonstrated selective WPT enhancement of ~10X and selective WPT denial of greater than…

Millimeter-Wave Compressive Imaging with Metamaterial Antennas

We have developed novel compressive imaging approaches in the millimeter wave bands (18-26 GHz, 85-110 GHz) using metamaterial antennas. The metamaterial antennas are designed to exploit extreme frequency diversity in their radiated modes to enable rapid single-shot image reconstruction from sparse measurements. Applications include spaceborne imaging radars as well as indoor personal security.

Privacy and The Value of Information

Tightly coupled with the operation of large-scale urban infrastructure is a diverse set of socioeconomic factors. A significant amount of data is being collected from these systems. This data, on the one hand, is utilized in improving system performance; on the other hand, it potentially exposes sensitive information. We are quantifying the value of the…

Transition Metal Oxide Electronic Devices

This work investigates the potential of transition metals oxides, in particular V2O5, for its application to data storage, optical switching and reversible electrochromic behavior. An on-going collaboration with Fumio Ohuchi (UW Materials Science and Engineering) and M. P. Anantram.
