Can you step twice in the same river? “Surely not!” would answer Heraclitus of Ephesus, the famous Ionian philosopher. If everything in nature flows, however, why should you trust your metamaterial to always stay the same? You shouldn’t, indeed, as we learn in this issue of the magazine! Prof. Andrea Alù, in fact, is our guest editor for an incredibly interesting and informative special issue on time-varying metamaterials. I am very grateful to Prof. Alù for his successful efforts in collecting a great roster of astonishingly high-quality articles from top experts of the discipline, providing an impactful overview of the topic. Enjoy the reading!
Are you enjoying the special issues of the magazine? The next could come from you! Special issues and sections include up to six articles to appear in a single issue of the magazine. Special series, instead, run for several issues (one or two articles per issue). The focus of special issues/sections/series could be on either established or emerging research topics relevant to the IEEE Antennas and Propagation Society. It goes without saying that we are also quite interested in interdisciplinary topics. You can send your proposal to apm-eic@ieee.org with 1) a title and a short abstract; 2) a list of prospective guest editors, with affiliations; and 3) a tentative list of potential contributors. We are looking forward to hearing from you!
It is with sorrow that we have learned of the passing of Prof. Rodolfo Zich, from Politecnico di Torino. Our thoughts and prayers go to him, his family, and his friends. Prof. Zich is honored in this issue of the magazine with an “In Memoriam” column [A1] from Prof. Roberto Graglia, on page 126.
In the final phases of preparing this issue, we also learned of the passing of Prof. Matteo Pastorino, from the University of Genoa. Prof. Pastorino had been an associate editor of the magazine, and this news leaves the entire editorial board in deep sadness. An “In Memoriam” column honoring him will appear in a future issue of the magazine.
