Guest Editorial: Programmable Metamaterials for Software-Defined Electromagnetic Control

摘要

This Special Issue of the IEEE Journal on Emerging and Selected Topics in Circuits and Systems (JETCAS) is dedicated to novel contributions to the field of programmable metamaterials. Recent years have witnessed the emergence of this paradigm, whereby the electromagnetic response of the metamaterial can be encoded into a string of bits. This allows to control electromagnetic waves using well-defined software directives and, further, to incorporate and combine them within systems to give rise to a plethora of new applications in fields such as sensing, wireless communications, or holography.
