Computational Electromagnetics for Metamaterial Modelling - Toru Uno;Naobumi Michishita;Takuji Arima

Electromagnetic metamaterials are a class of artificial media that exhibit electromagnetic properties not found in naturally occurring materials. The field of metamaterials has advanced rapidly, driven by theoretical and experimental investigations conducted predominantly in the optical field. Subsequent progress in microwave and terahertz component design has further accelerated this development, and numerous applications have since emerged in antenna engineering and electromagnetic compatibility. As a result, there is a strong demand for accurate and computationally efficient numerical techniques that support the design of electromagnetic devices incorporating metamaterials while ensuring satisfactory performance and reliability.

This book is organised around three objectives. Firstly, it introduces the principal computational methods for electromagnetic field analysis and explains their fundamental principles together with selected practical guidance to avoid modelling errors. Secondly, it presents recently developed techniques for the efficient analysis of metamaterial structures. Thirdly, it offers concrete examples of how computational methods may be appropriately incorporated into the design and analysis of metamaterial devices.

Computational Electromagnetics for Metamaterial Modelling offers a systematic and practical guide to using advanced computational and mathematical techniques to model metamaterials. It will be of value to researchers in the field of electromagnetics and to those with an interest in electronic and magnetic materials and metamaterials.

This book introduces the principal computational methods for analysing electromagnetic fields. Advanced and novel techniques for analysing metamaterial structures are presented, and explanations offered for the introduction of computational methods into the design of metamaterial devices through the use of concrete examples.
