If you are looking for the original "seminar papers" that birthed the field (often discussed within the book), researchers typically refer to these three: Metamaterials: Theory, Design, and Applications
: Theoretical designs and experimental verification techniques. Metamaterials: Theory, Design, and Applications
: It introduces optical transformation theory, which is the mathematical framework used to design materials that control electromagnetic wave flow. If you are looking for the original "seminar
: Development of beam splitters, concentrators, and new antenna types. and new antenna types.
