A collaboration between Jon Camden, an associate professor in the Department of Chemistry and Biochemistry, David Masiello of the University of Washington, and Philip Rack of the University of Tennessee has directly observed hybridized magnetic resonances in plasmonic nanostructures for the first time.
The achievement is a critical step toward developing materials that interact with light in unexpected ways and that may someday cloak military equipment throughout the visible spectrum or underlie future PV technology optimized to capture energy from the sun’s infrared rays. Their paper on the work, “STEM/EELS Imaging of Magnetic Hybridization in Symmetric and Symmetry-Broken Plasmon Oligomer Dimers and All-Magnetic Fano Interference,” was published in the American Chemical Society’s Nano Letters.
Camden and Masiello started their investigation years ago to understand how plasmonic nanostructures transfer energy into their surroundings. Masiello’s group focuses on theory and simulations to make predictions that they send to Camden, who uses sophisticated spectroscopic equipment – involving electron microscopes and lasers – to test the predictions in the real world.
