There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Title: Nonlinear RF/Microwave Circuit Design for Wireless Power Transfer and Energy Harvesting for Zero-Power Autonomous IoT and Smart City Applications
Abstract:
The need for mechanisms to achieve self-sustained devices and sensors towards implementing the concepts of the Internet of Things (IoT) and smart cities is a great concern in today’s society. The autonomy of devices and sensors is possible by considering wireless power transmission or energy harvesting solutions that allow powering up devices eliminating the use of batteries and the cost associated to their maintenance. During this multi-disciplinary presentation several energy harvesting and wireless power transmission solutions towards achieving the goal of self-sustainability will be shown, including improved efficiency topologies and waveform optimization. In the same direction of creating more energy efficient wireless systems, the signal generation and amplification is another important topic. In this presentation, bifurcation control for fast and accurate stability analysis in power amplifiers will be introduced as well as numerous novel topologies of coupled oscillator arrays for high frequency signal generation and beam steering exploring substrate integrated waveguide technology will be thoroughly discussed. The presented circuit designs find application in the frame of IoT, and 5G systems placing emphasis on energy efficiency and energy autonomy.
