The book focuses on the topology optimization method for nano-optics. Both principles and implementing practice have been addressed, with more weight placed on applications. This is achieved by providing an in-depth study on the major topic of topology optimization of dielectric and metal structures for nano-optics with extension to the surface structures for electromagnetics. The comprehensive and systematic treatment of practical issues in topology optimization for nano-optics is one of the major features of the book, which is particularly suited for readers who are interested to learn practical solutions in topology optimization. The book can benefit researchers, engineers, and graduate students in the fields of structural optimization, nano-optics, wave optics, electromagnetics, etc.

Metasurfaces are ultrathin optical elements that are highly promising for constructing lightweight and compact optical systems. In order to enhance the capabilities of the technology beyond what is achievable with conventional optics, I introduce a method for designing free-space metasurfaces via adjoint topology optimization. Using silicon on glass as a platform, I demonstrate that the optimization of wavelength-scale sections can be used to construct both periodic and aperiodic optical devices. For periodic devices, I show the process for optimizing a polarization-insensitive grating which efficiently deflects light to 75 degrees, as well as gratings which are capable of independently splitting up to 5 separate wavelengths. For aperiodic devices, I demonstrate the process by which we construct large objects, such as lenses, using wavelength-scale sections that are individually optimized to deflect to specific angles with a specified phase delay. Overall, we envision that the proper application of optimization techniques to free-space metasurfaces can realize their usage in enabling technologies requiring compact control over multiple distinct channels of light.

Electromagnetic metamaterials are a family of shaped periodic materials which achieve extraordinary scattering properties that are difficult or impossible to achieve with naturally occurring materials. This book focuses on one such feature of electromagnetic metamaterials—the theory, properties, and applications of the absorption of electromagnetic radiation. We have written this book for undergraduate and graduate students, researchers, and practitioners, covering the background and tools necessary to engage in the research and practice of metamaterial electromagnetic wave absorbers in various fundamental and applied settings. Given the growing impact of climate change, the call for innovations that can circumvent the use of conventional energy sources will be increasingly important. As we highlight in Chapter 6, the absorption of radiation with electromagnetic metamaterials has been used for energy harvesting and energy generation, and will help to reduce reliance on fossil fuels. Other applications ranging from biochemical sensing to imaging are also covered. We hope this book equips interested readers with the tools necessary to successfully engage in applied metamaterials research for clean, sustainable energy. This book consists of six chapters. Chapter 1 provides an introduction and a brief history of electromagnetic wave absorbers; Chapter 2 focuses on several theories of perfect absorbers; Chapter 3 discusses the scattering properties achievable with metamaterial absorbers; Chapter 4 provides significant detail on the fabricational processes; Chapter 5 discusses examples of dynamical absorbers; and Chapter 6 highlights applications of metamaterial absorbers.
