Mapúa University’s (MU) Department of Physics, in collaboration with Osaka University’s Institute of Laser Engineering (OU-ILE) and the National Institutes for Quantum and Radiological Science and Technology (QST), held a physics seminar last March 19 at the university’s seminar room.
Dr. Akira Sasaki, senior principal researcher at QST, gave the first lecture entitled “Theory and Numerical Simulation of Optical Damage Based on the Percolation Theory” where he discussed the numerical investigation of laser-induced damage. In his study, he quantified the damage brought by an intense laser beam on interconnected macroscopic cells represented by resistors that connect to a network of adjacent cells.
Throughout his career, Dr. Sasaki has dedicated his research interests mainly towards laser technology, radiation hydrodynamics simulation, extreme ultraviolet lithography, and the atomic process and radiative properties in plasmas.
A second lecture was given by Dr. Makoto Nakajima, an engineering graduate and an associate professor at OU, entitled, “Terahertz science and applications: From the introduction of new THz light to terahertz spintronics.” He elaborated on terahertz waves – waves with wavelengths from 1 mm to 0.1 mm. Delving further into the topic, terahertz lights sources and terahertz spintronics were discussed. The Osaka University graduate also discussed the applications of terahertz on time domain spectroscopy and security check systems in airports.
Dr. Nakajima has dedicated his research over the years in studies ranging from optical engineering and photon science, mathematical physics, and fundamental theory of condensed matter physics to applied physical properties.
On April 22, 2017, the University signed an Academic Exchange Agreement with OU-ILE which paved the way for the aforementioned seminar. According to Dr. Jacqueline Gabayno of the Physics Department, the aim of the said event is to strengthen the existing academic relationship and potential research collaborations between the involved universities.
