As a robotics engineer, Yasemin Ozkan-Aydin, assistant professor of electrical engineering at the University of Notre Dame, gets her inspiration from biological systems, including ants, honeybees and birds. Researchers previously have developed aerial and underwater robots that mimic the …
The explosion of wireless applications enabled by advanced radio technologies has placed access to a key natural resource, the radio frequency spectrum, at a premium. In the United States and around the world, radio frequencies are allocated to a variety of services such as mobile broadband, …
Reconstructing the entire spectrum of light from complex sources is vital for a number of applications — from medical imaging and drug development to national security. David Burghoff, assistant professor of electrical engineering, and his team have developed a new technique that provides an …
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 …
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 …
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 …
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 …
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 …
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 …
