Imaging at nanoscale using visible frequency spectrum has always been a challenging aspiration for optics community. The advent of plasmonics has given a great opportunity to engineer and invent optical devices using unconventional materials and methods that can manipulate light at nanoscale dimensions. In this book, Dr. Inampudi emphasize the principles of imaging devices using plasmonic diffraction elements and numerically demonstrate the capabilities of these devices to resolve objects with nanoscale resolutions. It includes a detailed numerical methodology to compute electromagnetic...
