THERMAL METAMATERIALS: CONTROLLING THE FLOW OF HEAT

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. Contents: Introduction Steady-State Heat Transfer: Transformation Thermotics Effective-Medium Methods Time-Harmonic Heat Transfer: Scattering of Thermal Fields Temporal Modulation Transient Heat Transfer: Effective Hamiltonian and Thermal Modes Thermal Lattices Outlook Readership: This book is suitable for undergraduate and graduate students in physics, materials science, mechanical engineering, and other majors related to thermal science and heat transfer. It can also serve as a reference for interested researchers and faculty.
