This Month's Highlights

The July issue of the IEEE Microwave Magazine is out! And I hope you made it to IMS2025 in San Francisco. The workshops, the papers, the exhibits, the events – it was big. Next year IMS will be in Boston. Bring your walking shoes and enjoy the city! This issue features wireless power transfer and we are not just talking about a few watts and short range. Things are changing in the wireless power transfer (WPT) community. For all the news on this issue please check out the Editor’s Desk column but for now we will try to give you a short tour of the issue. And check out the Guest Editor’s Desk for a better perspective on the features.

Our five features give a great overview of what is happening in wireless power transfer (WPT). Of course rectifiers are fundamental to WPT and we have a feature on all the latest in rectifiers. Our system features begin with the latest in powering the Internet of Things. While outdoor power transfer is a huge opportunity, one feature discusses indoor WPT. And WPT can also happen in space and over long distances which is yet another feature and a growing discipline. Our international magazine often specializes in what is happening in a given country and one of our features is all about WPT in the United Kingdom. As well as features this issue has two Application Notes. The first covers recognizing a transmitter by its signal characteristics or fingerprint. The second App Note is more personal as it covers the microwave detection of blood lactate. Microwaves can be good for you.

We have a full set of columns in this issue. Our President’s Column begins with our emphasis on education and interconnection. Our MTT-S Society News is all about our WPT technical committee, connections and our Inter-Society Technical Panels. We are an international society and our Around the Globe column welcomes everyone to the 28th European Microwave Week. We mentioned that microwaves can be good for you and our society has a special interest group just on Humanitarian Technology. Check out our MGA News column to learn more. Our chapters are fundamental to our operation and our Featured MTT-S Chapters column is a new way to keep updated. This month’s column features the Balkans. We have a number of Affinity groups. Women in Microwaves has become a regular column and this issue focuses on privacy awareness. A second Affinity group is the Young Professionals and their column reviews their 2025 Radio & Wireless Week.

A big part of Microwave Week is the after hours discussions on technology. Our columns mirror this in MicroBusiness with thoughts on how we can improve things. Microwave Surfing is always fun for a mental exercise and this column is about our search for extraterrestrial intelligence. Remember books? They even work when the Internet is down. Our Book/Software Reviews covers a new book on Fields and Waves in Electromagnetic Communications. We love our educators and this Educator’s Corner column covers transmission line kits and NanoVNAs. Finally our Enigmas, etc. problem takes on inductive power transfer which is right in line with this issue.

And don’t forget to check out the Conference Calendar! The in person events are the best!

About the journal

The IEEE Microwave Magazine is published monthly, with the IMS Special issue in April or May, and an RWW Supplement delivered with the December issue. The Microwave Magazine focuses on the publication of general interest review, tutorial, and survey papers rather than new research.

Most issues of the Microwave Magazine include a “focus section,” in which the technical features are invited by the guest editor, who is an acknowledged expert in the focus topic. The magazine also contains submitted technical articles, either as features or application notes. The technical content of the magazine is about 55 pages per issue, consisting of 4-5 feature articles and 1-2 application notes. Additionally, the magazine contains a number of regular columns, as well as editorial and news items.

The magazine has won two international awards for technical art from the Society for Technical Communication. The current impact factor for IEEE Microwave Magazine is 3.6 (2023). The magazine welcomes review, tutorial, and survey manuscripts in all topics of interest to the microwave engineering community; the time from submission to publication is under 26 weeks. Articles published in the Microwave Magazine are available to digital subscribers through IEEE Xplore.

For submissions, please read the Guidelines for Authors and submit your article via the IEEE Author Portal at https://ieee.atyponrex.com/journal/mttmm
