BATON ROUGE, LA – LSU Chemical Engineering Professor Kevin McPeak and Jon Wilson—LSU Chemical Engineer class of 2017, now pursuing his PhD in Chemical Engineering at the University of Delaware—recently published in Optics Express, the scientific journal of the Optical Society.

McPeak and Wilson co-authored the paper with Philipp Gutsche, Sven Herrmann, and Sven Burger of Zuse Institute Berlin. Gutsche is also on staff in the Department of Mathematics and Computer Science at the Free University of Berlin.

The article, titled “Correlation of Circular Differential Optical Absorption With Geometric Chirality in Plasmonic Meta-Atoms,” reports a strong correlation between the calculated broadband circular differential optical absorption (CDOA) and the geometric chirality of plasmonic meta-atoms with two-dimensional chirality. The group writes that this correlation holds for both contiguous plasmonic meta-atoms and non-contiguous structures, which support plasmonic coupling effects. A potential application for this correlation is the rapid optimization of plasmonic nanostructure for maximum broadband CDOA.
