Quantum phenomena are attracting increasing interest in various areas within electromagnetics. The article “Plasmonic Waveguides: Enhancing Quantum Electrodynamic Phenomena at Nanoscale,” by Ying Li and Christos Argyropoulos, continues this series on quantum technologies. While the article aims to explain plasmonic phenomena (sources near metal surfaces) at a quantum level, it also devotes significant attention to the use of the classical Green’s function in rigorous quantum theory and calculations. This provides a bridge from the familiar (classical electromagnetics) to what may be, for some readers, the unfamiliar (quantum electromagnetics) for dispersive and lossy environments.

电磁学中的量子现象[客座社论]

量子现象在电磁学的各个领域引起了越来越多的兴趣。Ying Li 和 Christos Argyropoulos 撰写的“等离子体波导：在纳米尺度上增强量子电动力学现象”一文继续介绍量子技术系列。虽然这篇文章旨在在量子水平上解释等离子体现象（靠近金属表面的源），但它也非常关注经典格林函数在严格的量子理论和计算中的使用。这为一些读者提供了从熟悉的（经典电磁学）到可能是不熟悉的（量子电磁学）分散和有损环境的桥梁。
