This book gives a comprehensive review on thermal metamaterials, an emerging type of artificial structures designed for the control of heat transfer. To date, many exciting findings have been made in this field, including some novel understandings about the heat transfer processes (reciprocity, symmetry, topological properties, etc.), as well as promising new possibilities to control heat (cloaking, rectification, collection, etc.). The text is organized into three segments: steady-state, time-harmonic, and transient heat transfer. In Part I, the transformation theory and effective medium method are introduced with their applications on the manipulation of steady-state heat transfer, covering early studies in this field. In Part II, the recently developed thermal scattering theory and temporal modulation method are discussed in the context of controlling time-harmonic heat transfer. In Part III, the effective Hamiltonian method is presented to study the decaying thermal modes in transient heat transfer. We include detailed derivations and examples for each theory or method. The book ends with an outlook chapter on open problems and potential possibilities in this promising field.

'The authors have played indispensable roles in highlighting the field's importance through their contributions to thermal metamaterials. This book provides a comprehensive and insightful overview of landmark contributions and is suitable for both experts and novices.' - Jiping Huang Professor and Vice-Dean, Department of Physics, Fudan University, China

'The area of thermal metamaterials is comparatively new. As such, this monograph is timely and welcome. The approach taken here, organizing the discussion based on the nature of heat transfer processes, is markedly different from existing literature that focus on the characteristic length of heat transfer.' - Teik-Cheng Lim Associate Professor, Singapore University of Social Sciences, Singapore
