Announcing: PhD Dissertation Defense Name: Peng Wu Title: Bayesian Data Fusion for Distributed Learning Date: 4/12/2024 Time: 12:30:00 PM Location: ISEC 532 Committee Members: Prof. Pau Closas (Advisor) Prof. Deniz Erdogmus Prof. Lili Su Abstract: The necessity for distributed data fusion arises from the increasing demand to integrate diverse and voluminous data sources, especially in applications where large numbers of users are collaborating to perform inference and learning tasks. This integration is crucial when data is available in a distributed…

Name: Lin Deng Title: Function Capacity Expansion of Nano-Optics via Multiplexed Metasurfaces Date: 4/15/2024 Time: 1:30:00 PM Location: SL 011 Committee Members: Prof. Yongmin Liu (advisor) Prof. Hossein Mosallaei Prof. Sunil Mittal Abstract: Throughout history, the exploration of light has been fundamental to our understanding of the world and has driven advancements in technology and communication. Metasurfaces, composed of rationally designed nanostructures, offer a revolutionary means to control light in a prescribed manner. Metasurfaces can operate in conventional free space,…

Name: Nolan Pearce Title: Downlink Transmit Beamforming: Single-Carrier Acoustic Communication in a Noisy Environment Date: 4/16/2024 Time: 2:00:00 PM Location: EXP-601A: Committee Members: 1. Prof. MIlica Stojanovic (Advisor) 2. Prof. Stefano Basagni 3. Prof. Josep Jornet 4. Dr. Dimitrios Koutsonikolas Abstract: Noisy wireless acoustic channels produce intersymbol interference (ISI) from multipath propagation. This interference may be reduced by equalization techniques but require computationally intensive receiver algorithms. Typically, beamforming methods are implemented at the uplink receiver to reduce complexity of equalization…

Name: Zihan Wei Title: Spatial Correlation Based Broadband Acoustic Beamforming Date: 4/16/2024 Time: 3:00:00 PM Location: EXP-601A Committee Members: 1. Prof. Milica Stojanovic (Advisor) 2. Prof. Stefano Basagni 3. Prof. Josep Jornet Abstract: This thesis presents a spatial correlation based broadband acoustic beamforming approach, addressing significant challenges pertains to acoustic communication channels, such as time-varying multipath propagation and volatile phase fluctuations due to surface reflections. The proposed beamforming approach utilizes the synchronization preamble, a high-resolution pseudo-random sequence, to estimate the…

Announcing: MS Thesis Defense Name: Ruopeng Jia Title: Engineering Super-modes of Coupled Ring Resonator Arrays Date: 4/19/2024 Time: 2:00:00 PM Committee Members: 1) Sunil Mittal (Advisor) 2) Prof. Yongmin Liu 3) Prof. Ghosh Siddhartha Abstract: In the past year of learning and research, we have mastered the ability to analyze and modulate various resonant ring structures using Hamiltonian operators. Using genetic optimization algorithms, we have achieved a precisely controllable four wave mixing process under simulated conditions.
