超材料研究是一项极其重要的全球性活动，有望以许多不同的方式改变我们的生活。其中包括使物体隐形，以及超材料对社会能源和医疗部门的巨大影响。然而，在所有这些应用的背后，是创造出一种不会被共振反应所导致的损耗所破坏的超材料。这篇综述提出了一些解决方案来管理损失和增益，耦合到控制和非线性行为，并讨论了一些关键的后果有关的稳定性。在活性和可调超材料的总标题下，国际范围的作者在这里合作，提出了一套解决方案，从几个方向解决这些问题。正如大家所认识到的，各种可能的解决办法确实令人着迷，希望这些讨论将进一步促进这一领域的发展。
Metamaterial research is an extremely important global activity that promises to change our lives in many different ways. These include making objects invisible and the dramatic impact of metamaterials upon the energy and medical sectors of society. Behind all of the applications, however, lies the business of creating metamaterials that are not going to be crippled by the kind of loss that is naturally heralded by use of resonant responses in their construction. This review sets out some solutions to the management of loss and gain, coupled to controlled and nonlinear behavior, and discusses some critical consequences concerning stability. Under the general heading of active and tunable metamaterials, an international spectrum of authors collaborates here to present a set of solutions that addresses these issues in several directions. As will be appreciated, the range of possible solutions is really fascinating, and it is hoped that these discussions will act as a further stimulus to the field.
