Illinois ECE graduate student Shen Lin recently won third place at the IEEE International Symposium on Antennas and Propagation (AP-S) Student Paper Competition. The IEEE International Symposium on Antennas and Propagation (AP-S) is the premier international forum for the exchange of ideas on state-of-the-art research in antennas and propagation and radio science. The student paper competition in the symposium is extremely competitive with 203 student papers entering the competition. Advised by Illinois ECE Associate Professor Zhen Peng, Shen Lin is a PhD student at the Center for Computational Electromagnetics.

As Internet of Everything infrastructures emerge, it is expected to connect more than thousands of devices within a confined indoor environment contending for the limited electromagnetic spectrum. The growing demand for data traffic meets confined space and congested spectrum creates a clear and present technical challenge. Thus, there has been much interest in studying the physics of wireless channels in strongly scattering, indoor environments.

Shen Lin and Peng presented a physics-based mathematical model, a so-called stochastic Green’s function, to characterize the channel capacity, coherence bandwidth, and power delay spread using the macroscopic knowledge of the propagation environment.

The proposed stochastic wave model serves as a promising mathematical tool for the communication-theoretic understanding of information transmission in the high-frequency indoor channel. The research applications include holographic MIMO and intelligent surfaces, space-frequency division, multiplexing, and near-field indoor communication.

Their work is funded by an NSF CAREER award.
