2023, Experimental Demo at Brooklyn 6G Summit

Our group conducted a live experimental demo at the Brooklyn 6G Summit. In this demo, we presented a hybrid classical-quantum computing framework for solving the joint channel estimation and optimization problem for RIS-assisted wireless communications. Our demonstration included transmitter and receiver antennas with no line-of-sight link while using an RIS to create a virtual line-of-sight link. The antennas are connected to USRP N210 Software Defined Radio (SDR). An interactive interface is provided to plot in real time the configuration of the RIS, channel gain, received constellation, and decoded message data.

2023, Best Student Paper Award (2nd prize) at NEMO’2023

Charles Ross received the Best Student Paper Award (2nd prize) at the IEEE MTT-S International Conference on Numerical Electromagnetic and Multiphysics Modeling and Optimization (NEMO). The title of the paper is “A Hybrid Classical-Quantum Computing Framework for RIS-assisted Wireless Network”.

By leveraging the computing power of quantum adiabatic evolution and mathematics of tensor contraction, the onsite optimization of RIS configuration can be performed rapidly using only feedback (received power) at wireless endpoints. The outcomes enable the possibility of ultrafast joint channel estimation - optimization in dynamic wireless environments.

2022, Best Electromagnetics Paper Award at 16th European Conference on Antennas and Propagation

We proposed a physics-based optimization approach for reconfigurable intelligent surfaces, inspired by the quantum mechanical physics of correlated spins. The new idea is grounded on the isomorphism between the electromagnetic scattered power and Ising Hamiltonian. Thereby, the problem of optimizing phase configuration is converted into finding the ground state of the target Ising Hamiltonian. Under this framework, we successfully demonstrated the feasibility of combinatorial optimization for weighted beamforming and diffusive scattering applications.

The model characterizes both spatial and temporal variations and correlations of wave fields without the need for detailed knowledge of the complex environment. Experimental results are supplied to validate the proposed work.

2020, 3rd Place Winner in Student Paper Competition at IEEE AP-S Symposium

Our Paper “Statistical Analysis of Information Transmission in Ray-Chaotic Enclosures: A Stochastic Green’s Function Approach” (Shen Lin and Zhen Peng) won the 3rd place in Student Paper Competition (SPC) at 2020 IEEE International Symposium on Antennas and Propagation and North American Radio Science Meeting (2020 IEEE AP-S). A total of 203 student papers entered into the SPC this year.

There has been much interest in studying the physics of wireless channels in strongly scattering, indoor environments displaying ray chaotic dynamics. This paper presents a physics-based mathematical model, so-called stochastic Green’s function, built upon Wigner’s random matrix theory and Berry random wave hypothesis. The work can be used to characterize the channel capacity, spatial correlation, and coherence bandwidth based on macroscopic knowledge of the propagation environment.

2019, Best Conference Paper Award at 28th Electrical Performance of Electronic Packaging and System

Our Paper “A Novel Space-Time Building Block Methodology for Transient Electromagnetic Analysis” (Shu Wang and Zhen Peng) received the Best Paper Award at 28th Electrical Performance of Electronic Packaging and System (EPEPS2019). 

We proposed a space-time building block methodology for efficient time-domain analysis of multi-scale, locally periodic structures. By leveraging the principles of linear superposition and space-time causality in wave physics, the 4D simulation domain is represented by a few space-time building blocks, which are constructed upon 3D spatial unit cell and 1D time unit. The work results in novel time-evolution schemes, which exhibit high-order accuracy and achieve concurrency and parallelism in both spatial and temporal dimensions.

2019, 1st Place in Student Paper Competition at ACES Symposium

Shu Wang received the 1st place in the student paper competition at 2019 International Applied Computational Electromagnetics Society (ACES) Symposium. The title of the paper is “Platform-aware In-situ Antenna and Metamaterial Analysis and Design”. Congratulations to Shu!

The objective of this paper is to build a reconfigurable, reusable, and parallel model reduction platform towards transformative in-situ antenna design. The key idea is to introduce a separable and compressible platform Green’s function in an up-front offline computation. Once obtained, the online computational complexity does not depend on the size of the in-situ platform. As a result, in-situ design and optimization of multi-antenna systems can be performed at the same cost as the free-space radiation. The advancements make high-fidelity in-situ antenna design orders of magnitude faster. It is a joint work with Dr. Brian MacKie-Mason and Dr. Hongwei Gao.

2019 ACES Symposium Short Course

Ever-increasing fidelity and accuracy needs for advanced electromagnetic (EM) applications have been pushing the problem sizes toward extreme scales. It puts a high premium on the investigation of high-performance algorithms with optimal computational complexity. In recent years, domain decomposition (DD) methods have enjoyed considerable success in solving large multi-scale EM problems. These methods feature divide-and-conquer in solution algorithms (applying the most suitable solution strategy to solve each sub-problem) and plug-in-play in software architectures (integrating individual EM solvers into a portable and extensible solution suite). They also result in highly efficient and naturally parallelizable algorithms on distributed memory many-core parallel computing systems. 

This short course will review and discuss recent progress in the DD methods for solving differential and integral equations with applications to large-scale EM problems.
