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.

客座社论：用于软件定义电磁控制的可编程超材料

IEEE Journal on Emerging and Selected Topics in Circuits and Systems (JETCAS) 的这一特刊致力于对可编程超材料领域的新贡献。近年来见证了这种范式的出现，其中超材料的电磁响应可以编码为一串位。这允许使用定义明确的软件指令控制电磁波，并且进一步将它们合并和组合在系统中，从而在传感、无线通信或全息等领域产生大量新应用。
