Development of bioinspired materials and metamaterials has changed the philosophy of materials engineering and opened new technological possibilities, as they demonstrate properties that are not found in naturally occurring materials. This book examines advances in these emerging materials classes and investigates how their tailor-engineered properties, such as specific surface energy or refraction index, enable the design of devices and ultimately the ability to solve complex societal problems that are, in principle, impossible with traditional materials.The aim of this book is to survey the scientific foundations of the design and properties of bioinspired materials and metamaterials and the way they enter engineering applications.Introduces the physico-chemical foundations, theoretical groundings, and main equations of biomimetic and metamaterials scienceDescribes how to develop and design these advanced materials and their applicationsFeatures end-of-chapter problems to help readers apply the principlesSurveys achievements including metamaterials cloaking and the negative mass effectEmphasizes ecological aspects of materials scienceThe text is intended for materials engineering students who have completed courses in general physics, chemistry, and calculus, as well as researchers in materials science and engineering.
