"This book introduces fundamental principles as well as applications of metasurfaces, i.e. electromagnetically thin structures manipulating EM wave propagation. The authors describe the precursors and history of metasurfaces before moving on to explore the physical insights that can be gained from the material parameters of the metasurface. They also present how to compute the fields scattered by a metasurface, with known material parameters, being illuminated by an arbitrary incident field, as well as how to realize a practical metasurface and relate it its material parameters to physical structures.The book finishes with a discussion of the future of the field"--

Discover a comprehensive exploration of recent developments and fundamental concepts in the applications of metasurfaces.

In Electromagnetic Metasurfaces: Theory and Applications, distinguished researchers and authors Karim Achouri and Christophe Caloz deliver an introduction to the fundamentals and applications of metasurfaces and an insightful analysis of recent and future developments in the field. The book describes the precursors and history of metasurfaces before continuing on to an exploration of the physical insights that can be gleaned from the material parameters of the metasurface.

You’ll learn how to compute the fields scattered by a metasurface with known material parameters being illuminated by an arbitrary incident field, as well as how to realize a practical metasurface and relate its material parameters to its physical structures. The authors provide examples to illustrate all the concepts discussed in the book to improve and simplify reader understanding.

Electromagnetic Metasurfaces concludes with an incisive discussion of the likely future directions and research opportunities in the field.

Readers will also benefit from the inclusion of:

  • A thorough introduction to metamaterials, the concept of metasurfaces, and metasurface precursors
  • An exploration of electromagnetic modeling and theory, including metasurfaces as zero-thickness sheets and bianisotropic susceptibility tensors
  • A practical discussion of susceptibility synthesis, including four-parameters synthesis, more than four-parameters synthesis, and the addition of susceptibility components
  • A concise treatment of scattered-field analysis, including approximate analytical methods, and finite-difference frequency-domain techniques

Perfect for researchers in metamaterial sciences and engineers working with microwave, THz, and optical technologies, Electromagnetic Metasurfaces: Theory and Applications will also earn a place in the libraries of graduate and undergraduate students in physics and electrical engineering.
