Diffraction Based High Resolution Imaging Devices

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 properties of various Cartesian coordinates based geometries such as rectangular slits and diffraction gratings. This book is ideal for applied physicists entering into the field of computational imaging and this volume gives an overall understanding of the design of materials and devices to enhance image and focus light at subwavelength scale. The proposed techniques have potential applications in the fields of on-chip optical circuitry biological sensing security material characterization and optical sensors.
