Reference excerpt

Supriyo Bandyopadhyay is an Indian-born American electrical engineer, academic and researcher. He is Commonwealth Professor of Electrical and Computer Engineering at Virginia Commonwealth University. Bandyopadhyay has worked on a range of topics including spintronics, straintronics, nanoelectronics and related aspects of nanotechnology.

Education Bandyopadhyay received his B.Tech. degree in Electronics and Electrical Communications Engineering from Indian Institute of Technology, Kharagpur in 1980. He then earned his M.S. degree in Electrical Engineering from Southern Illinois University in 1982, and a Ph.D. degree in Electrical Engineering from Purdue University in 1985.

Career Following his Doctoral degree, Bandyopadhyay held a brief appointment as a Visiting Assistant Professor of Electrical Engineering at Purdue University before joining the University of Notre Dame in 1987 as an Assistant Professor of Electrical Engineering. From 1990 till 1996, he served as an Associate Professor there. He subsequently joined the University of Nebraska-Lincoln as a Professor of Electrical Engineering in 1996. In 2001, he joined Virginia Commonwealth University and held a primary appointment as Professor of Electrical Engineering in the Department of Electrical and Computer Engineering and courtesy appointment as a Professor of Physics in the Department of Physics. Since 2011, he has been serving as Commonwealth Professor Virginia Commonwealth University. Bandyopadhyay served as a Jefferson Science Fellow for the US National Academies of Science, Engineering and Medicine during 2020–2021 and was a Senior Adviser to the USAID Bureau of Europe and Eurasia in the Division of Energy and Infrastructure at Washington, DC. He is a member of the Institute of Electrical and Electronics Engineers (IEEE) Technical Committee on Spintronics (Nanotechnology Council), and past-chair of the Technical Committee on Compound Semiconductor Devices and Circuits (Electron Device Society). He was an IEEE Electron Device Society Distinguished Lecturer from 2005 to 2012, and was an IEEE Nanotechnology Council Distinguished Lecturer in 2017 and 2018.

Research Bandyopadhyay has worked on spintronics, straintronics, nanoelectronics, nanosynthesis, electrochemical self-assembly, quantum dots and nanowires, hot carrier and quantum transport of charge in solids, spin based quantum computing and classical spin-based logic circuits, spin transport in nanostructures, and spin-based devices and general topics in spintronics. Bandyopadhyay's most recent work has involved switching nanomagnets with electrically generated strain to produce energy-efficient digital information processing hardware. He worked in the field of hybrid spintronics and straintronics, His group harnessed straintronics to demonstrate an extreme sub-wavelength electromagnetic antenna that overcame the theoretical limits on antenna gain and efficiency and exceeded them by several orders of magnitude. He and his collaborators also conducted a study in 2021 to demonstrate resonant amplification of spin waves in a periodic two-dimensional interacting array of multiferroic nanomagnets which would have applications in magnonic devices.

Worked examples

Example 1 — a first encounter with Supriyo Bandyopadhyay

Start with the simplest possible case. Write down what Supriyo Bandyopadhyay claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Supriyo Bandyopadhyay before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Supriyo Bandyopadhyay ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Supriyo Bandyopadhyay

In research: Supriyo Bandyopadhyay appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Supriyo Bandyopadhyay in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Supriyo Bandyopadhyay is common in secondary-school and first-year university syllabi. It links to neighbouring topics American people of Bengali descent, Fellows of the American Physical Society, IIT Kanpur alumni, so understanding it makes those chapters shorter.
In everyday life: Look for Supriyo Bandyopadhyay outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
