Novel nanoscale structures have demonstrated a wide range of unique features; therefore have became a hot research topic. Not only that the novel structural materials are used in biomedical therapy, but also the nature inspires the design of innovative optical structures. In this book, we focus on recent developments of theoretical analysis, designs of novel nano-photonic structures and functional materials for optical instrumentation. This book is constituted of 10 chapters contributed by renowned researchers from all over the world who work in the forefront of this field.
