A powerful, pocket-sized optical imager, no longer science fiction

Before Wilhelm Röntgen, a mechanical engineer, discovered a new type of electromagnetic radiation in 1895, physicians could only dream of being able to see inside the body. Within a year of Röntgen’s discovery, X-rays were being used to identify tumors. Within 10 years, hospitals were using …

Electrical engineering team spotlighted for work developing a new kind of semiconductor memory

The work of a Notre Dame electrical engineering research team — including graduate students Wriddhi Chakraborty, Jorge Gómez Mir, and Huacheng Ye — was featured in vivid color in IEEE Spectrum, the flagship magazine and website of the IEEE, the world’s largest professional organization …

Untangling the potential of frequency-modulated combs

A frequency comb is a laser with a twist that emits many uniformly spaced optical wavelengths. The regularity of the spacing between lines — the comb’s teeth — serves as a ruler for measuring light frequencies. David Burghoff, assistant professor of electrical engineering, developed a …

SpectrumX – Universities join forces to pursue NSF center opportunity

Four teams awarded planning grants through the National Science Foundation’s (NSF’s) new Spectrum Innovation Initiative (SII) are merging to create a comprehensive, interdisciplinary plan for a 5-year, $25M National Center for Wireless Spectrum Research (SII-Center). The envisioned center …

Engineers developing high-speed light detectors for closer look at the sun

For all that scientists have learned about the sun, plenty of unanswered questions remain about the brightest star in the sky. Advancements in solar astronomy have informed a basic understanding of the light spectrum and help predict geomagnetic storms capable of causing blackouts to electronic …

“Smart” breast clips: A new approach to breast cancer treatment

Breast cancer is the second most common cancer in American women and the second leading cause of cancer deaths in women, according to the American Cancer Society. In 2019 it claimed the lives of more than 41,000 women in the United States and changed the lives of 3.5 million breast cancer …
