During the PhD period, presence of second harmonic guided waves is explored and their significance is studied. Also the studies regarding the usage of metamaterial for harmonic suppression was done as an internal collaboration project. Presently, I'm exploring and having my hands on some new techniques such as PAUT, Thermography, Terahertz imaging as there are these equipments in the lab and taking the opportunity to get familiar with them. I'm also supporting new scholars or staffs who are working in ultrasonics when they are facing issues and solving together.
