2017 IEEE APS/URSI Student Paper Competition Finalists

Nandhini Srinivasan
Scholars out of the ElectroScience Laboratory (ESL) at The Ohio State University earned research awards this summer at the 2017 IEEE APS/URSI San Diego Symposium Student Paper Contest.

ESL Graduate Research Associate Nandhini Srinivasan won Third Place and a $300 cash award for her paper, “High-resolution Polarimetric THz Imaging for Biomedical Applications.”

The research, which seeks early detection of Alzheimer’s disease, was conducted under the guidance and assistance of faculty members Cosan Caglayan, Niru Nahar and Kubilay Sertel.

Srinivasan said her work explores a novel new approach for improving the imaging of human brain tissue samples to improve Alzheimer’s disease research.

“We initially examined different parts of the brain in THz frequency to come up with a method to distinguish brain samples with Alzheimer’s disease from normal brain samples,” Srinivasan said. “After successfully identifying that white matter region within the brain is the one being affected more in Alzheimer’s disease, we presented a new imaging topology capable of providing 3.4 times better resolution than the commercially available system.”

Srinivasan said this proposed system also facilitates the study of the features within the white matter regions of the brain, a region where Alzheimer’s disease seems to have the most impact.

“Right now, our system works as a pathological tool and measures autopsied tissue samples,” she said. “However, our ultimate aim is to provide an endoscopic form to facilitate measurement in a live person.”

What they have designed to date, she said, provides more efficiency and higher resolution than existing commercial systems.

Sertel said this year ESL had three students place among the top 13 finalists at the event, among 159 submissions worldwide. All three students received travel grants to attend the conference.

The other two finalists were:

• Syed An Nazmus Saqueb, a PhD candidate at ESL, whose research paper, “Single-bit Compressive Imaging System for the mmW and THz Bands” was written with Sertel. Saqueb worked on a single-pixel detector THz imaging system, which allows for a faster, more cost effective, and more efficient service than existing commercial imaging systems. It relies on low energy, non-ionizing THz radiation, he said, removing the inherent dangers associated with Xrays in biomedical and security applications.
• Qi Wang and his research paper, “Range-Dependent Evaporation Duct Height Estimation from a Versatile Ship-Mounted X-band Receiving Array,” written with Robert Burkholder, and Caglar Yardim. Wang is working via the larger multi-university research initiative (MURI) project called “CASPER,” or Coupled Air-Sea Processes and Electromagnetic Ducting Research. The project aims to advance naval communication systems, studying the reflectivity in the marine atmosphere and how it affects propagation.
