IEM Seminar Series: Millimeter-Wave and THz Integrated Circuits for Sensing and Imaging
Abstract
Thanks to advances in integrated circuit technology, operating at mm-wave and sub-THz frequencies has become more accessible than ever. As a result, we are witnessing the emergence of circuits and systems that leverage high-frequency electromagnetic fields and waves not only for their traditional roles in communication and radar, but also for emerging applications in sensing and imaging.
In this talk, I will present single-pixel and multi-pixel biosensing and imaging platforms that use resonator-based pixels. These pixels are compact and highly sensitive to perturbations of their local electromagnetic near-fields, induced by changes in the permittivity of biological samples. As a result, single-cell-level sensitivity can be achieved in sensing, and sub-wavelength (~λ/30) resolution in imaging. When integrated with microfabricated fluidic channels and packaging structures, these systems become powerful tools for detecting, characterizing, and analyzing cells and tissues, with permittivity serving as a natural contrast agent. The proposed technologies hold significant promise for real-time, cost-effective, and non-invasive diagnostic imaging.
Biography
Ali Ameri received his bachelor’s and master’s degrees in electrical engineering from the University of Tehran and McGill University, respectively. He then worked at Granite SemiCom, an IP company based in Toronto, where he focused on hybrid phase-locked loops and industrial sensor interfaces. After four years in industry, he joined the Department of Electrical Engineering and Computer Sciences at UC Berkeley, where he completed his Ph.D. and then pursued postdoctoral training. He is currently a research scientist at Bosch USA, where he works on high-precision analog/mixed-signal circuits for consumer electronics. His research interests include integrated circuits for communication, sensing, and imaging. He is also the recipient of the Principal’s Graduate Fellowship at McGill University and the H2H8 award at UC Berkeley.
