Wave Optics

Subhasish Dutta Gupta joined the School of Physics, University of Hyderabad, India in 1984, having received his education (integrated M.Sc and Ph.D) from Peoples' Friendship University, Moscow. Along with other core subjects, he has been teaching optics-related courses for undergraduate and graduate students for more than three decades. Moreover, he has been actively involved in research on the forefront areas of nonlinear and quantum optics, plasmonics, and nanooptics. He has authored one US patent, more than a hundred papers in peer-reviewed journals, several invited reviews, and book chapters. He has been a visiting faculty member at many reputed institutes on different continents. He served on the editorial board of Pramana–Journal of Physics, and is currently an associate editor of the European Physical Journal–Applied Physics.Nirmalya Ghosh is a physicist by training with further specialization in nano-optics and biophotonics. He received his Ph.D from Raja Ramanna Centre for Advanced Technology (RRCAT), Indore, India. Subsequently, he conducted his postdoctoral research in the Department of Medical Biophysics, University of Toronto, Ontario, Canada. He has also held the position of scientist at RRCAT in the Department of Atomic Energy. He is currently an associate professor in the Department of Physical Sciences, Indian Institute of Science Education and Research, Kolkata. Dr. Ghosh is the author and co-author of more than 50 papers in peer-reviewed international journals, several book chapters, and a number of invited reviews in the area of optics and photonics. He has been serving as an editorial board member of Scientific Reports. Ayan Banerjee has been working in the field of optics and spectroscopy for the last 17 years. He obtained his Ph.D in physics from the Indian Institute of Science, Bangalore, following which he was a research scientist at General Electric
