Congratulations to Himanshu Aggrawal, graduate student in the department of electrical and computer engineering, on being nominated for a Young Engineer Prize by the 2017 European Microwave Integrated Circuit Conference (EuMIC). In addition to the nomination, Himanshu received a student grant for the conference, to be held in Nuremberg, Germany.
A student in Dr. Aydin Babakhani’s Rice Integrated Systems and Circuits (RISC) Laboratory, Himanshu will travel to the conference to present his paper, titled, “A Nonlinear Impulse Sampler for Detection of Picosecond Pulses in 90 mm SiGe BiCMOS.”
Himanshu’s paper introduces a novel impulse-based sampling architecture for detecting ultra-short pulses, a key component in enabling next generation mm-wave receivers. His research focuses on Terahertz (THz) waves, which occupy the millimeter-wave band from 0.1mm to 1mm.
“THz waves are unique in the spectrum because of their potential applications in secure communications, laser free THz spectroscopy, and medical imaging. Despite the interest in using terahertz waves, we currently lack the underlying hardware platform to build upon,” Aggrawal explained.
“Himanshu is pushing the limits of high-speed samplers and receivers in the mm-wave regime with signal frequencies exceeding 60GHz. He is working on a novel nonlinear sampling idea that can reduce the sampling window to few picoseconds,” Babakhani said.
In 2016, IEEE recognized Himanshu’s work in next-generation THz millimeter wave technology by awarding him a prestigious MTT-S Graduate Fellowship. He has been nominated for multiple best paper awards and won an honorable mention at the 2014 IEEE International Microwave Symposium.
“Terahertz technology has the potential to engender significant societal change in the near future,” Aggrawal said. “For any of the proposed terahertz applications to come to fruition, we must first strive for quality terahertz transceivers. Through this research, our lab is in a unique position to make significant strides in developing this technology.”
