The Physics Department's Wave-Transport Lab recently received awards totaling $709,000 to support its ongoing aim to understand and manipulate the movement of waves—sound, mechanical, or electromagnetic—through natural or human-made materials. The lab received a $340,000 grant from the National Science Foundation's Division of Civil, Mechanical, and Manufacturing Innovation program titled "Engineering Dynamical Symmetries for Extreme Wave-Matter Interactions in Elastodynamics," and a $369,000 grant from the Department of Defense's Office of Naval Research (ONR) titled "Waveform Shaping Techniques for Targeted Electromagnetic Attacks." The Wave-Transport Lab was established in 2016 when Fred Ellis, chair and professor of physics, and Tsampikos Kottos, the…

On Sept. 3, during the first faculty meeting of the fall semester, three Wesleyan professors were honored with the Wesleyan Prize for Excellence in Research. The faculty-nominated prize is presented to members of the faculty who demonstrate the highest standards of excellence in their research, scholarship, and contributions to their field. Interim Provost and Senior Vice President for academic affairs Rob Rosenthal acknowledged the recipients during the faculty meeting. Each winner received a plaque and funding for his or her research. This year's recipients include: Natasha Korda, professor of English, plays a highly visible role in keeping scholarship on Renaissance…

Tsampikos Kottos, professor of physics, and Yaxin Li '19 are the coauthors of an article titled "Coherent Wave Propagation in Multimode Systems with Correlated Noise" published in the April 18, 2019 issue of Physical Review Letters. In this study, the coauthors utilize a random matrix theory approach to unveil a physical mechanism that shields wave coherent effects in the presence of disorder (noise).

Tsampikos Kottos, professor of physics, and Wesleyan University will lead a complex, multi-institution initiative to research and develop the next generation of national instrumentation technology thanks to a four-year, $2,794,606 grant from the Defense Advanced Research Projects Agency (DARPA). Awarded this August, the grant is the culmination of at least eight years of photonics research by Kottos and his fellow collaborators, and will have significant implications for the future of a variety of technologies employed by the federal government and the private sector. An agency of the U.S. Department of Defense, DARPA funds research and development projects that push the…

Tsampikos Kottos, professor of physics, professor of integrative sciences, professor of mathematics, was awarded a $400,000 Emerging Frontiers in Research and Innovation (EFRI) engineering grant from the National Science Foundation in October. This $2 million grant is equally split among a consortium of universities, including Stanford University, University of Minnesota, and University-Wisconsin-Madison, and will last for a period of four years. The grant is associated with “New Light and Acoustic Wave Propagation: Breaking Reciprocity and Time-Reversal Symmetry” (NewLaw) and supports “engineering-led interdisciplinary research that challenges the notions of reciprocity, time-reversal symmetry and sensitivity to defects in wave propagation and field transport,"…

With support from the Office of Naval Research, researchers in Wesleyan's Physics Department are working on ways to protect optical sensors (for example, the human eye) against laser-induced damage. In August, Tsampikos Kottos, professor of physics, professor of mathematics, received a three-year grant from the Office of Naval Research to further his designs of “Reflective Microwave Limiters." Typical microwave limiters have the ability to block excessive radiation through absorption. However, absorption can lead to overheating, eventually causing the destruction of the limiter. Kottos studies reflective power limiters with his graduate student Eleana Makri and Postdoctoral Research Associate Roney Thomas. The team hopes to develop realistic designs of microwave…

In its most recent meeting, the Board of Trustees conferred tenure on Hari Krishnan, associate professor of dance. He joins seven other faculty members who were awarded tenure earlier this spring. In addition, seven faculty members were promoted to Full Professor: Mary Alice Haddad, professor of government; Scott Higgins, professor of film studies; Tsampikos Kottos, professor of physics; Edward Moran, professor of astronomy; Dana Royer, professor of earth and environmental sciences; Mary-Jane Rubenstein, professor of religion; and Gina Athena Ulysse, professor of anthropology. Brief descriptions of their research and teaching appear below. Associate Professor Krishnan teaches studio- and lecture-based dance courses on Mobilizing Dance: Cinema, the Body, and Culture…

#THISISWHY For many years, pilots in the Air Force, scientists conducting research with high-powered lasers, and others have struggled to protect their eyes and sensitive equipment from being damaged by intense laser pulses. In many cases, this was achieved by intense power filters, which offered protection, but self-destructed. Now they have a solution, which provides protection without damaging the filters themselves, thanks to a research collaboration between the Air Force Research Laboratory (AFRL) and a team of researchers in Wesleyan's Physics Department. The research, led by Tsampikos Kottos, the Douglas J. and Midge Bowen Bennet Associate Professor of Physics, is included…

A study co-authored by Graduate Research Assistant Eleana Makri and two other Wesleyan researchers is a topic of a Oct. 20 article published in Scientific Reports. Due to the ultrahigh-speed and ultrawide-band brought by adopting photons as information carriers, photonic integration has been a long-term pursuit for researchers, which can break the performance bottleneck incurred in modern semiconductor-based electronic integrated circuits. The article states that "recently, Makri theoretically proposed the concept of reflective power limiter based on nonlinear localized modes, where a nonlinear layer was sandwiched by two reflective mirrors, thus increased the device complexity." The report is based on Makri's study, titled "Non-Linear Localized Modes Give Rise…

Tsampikos Kottos and Ali Basiri, a Ph.D. student in physics, are co-authors of a paper titled "Light localization induced by a random imaginary refractive index," published in Physical Review A 90, on Oct. 13, 2014. Kottos is the Douglas J. and Midge Bowen Bennet Associate Professor of Physics. In the paper, the authors show the emergence of light localization in arrays of coupled optical waveguides with randomness.
