The June issue of the IEEE Microwave Magazine is out! This issue is distributed at the IMS in Boston. This issue features electromagnetic modeling and optimization. The features in this issue are special and I will let you read the Editor’s Desk column to find out why. This issue is packed! As well as five features we have seven of the IMS2025 Student Design Competition winners. These design competitions get more sophisticated every year. And we have a full set of columns to peruse.

Starting with the features, we get to learn a lot about practical filter production and methods of achieving the desired result. One feature is all about extracting the coupling matrix for coupled resonator filters. Filters need the right amount of coupling as well as the right amount of resonator frequency tuning and the real world has tolerances. AI and neural networks can help us with managing the tolerances in our filter structures. Our first feature covers the use of a neuro-transfer function to assist our modeling. Simulation can take a lot of time for our 3D filter structures and while neural networks can speed this up so can advanced space mapping techniques such as those discussed in our third feature. As filters get more concerned with wide pass bands and wide stop bands our components benefit from parametric modeling and our fourth feature tells us how neural networks are helpful. Our last feature even goes beyond AI to quantum entanglement.

As mentioned before, our Student Design Competition winners cover a wide range of topics with increasing sophistication. Just as a quick overview, the winners cover a miniaturized magnetoceramic antenna, a switched acoustic filter module, various retroreflectors to assist rocket tracking, a pixelated band pass filter (which brings us back to parametric modeling of complex structures), the messy problem of wide band stop filter design (more complicated modeling), an efficient eGaN switching mode power amplifier and signal dependent predistortion of load modulated power amplifiers. We have come a long way from simple amplifier classes.

Next, please check out the columns. As mentioned before the Editor’s Desk will not only give you a tour of this issue, but also tell you why the features in this issue are special and how they relate to the future of the MTT-S. The President’s Column discusses something that is key to the symposium this month and that is the connection between industry, academia, and our future. This issue also has a couple of columns on recognition. We have an Awards column on the 2026 Fellows Elevation. Please check out their interesting achievements. And we have a Reviewer Recognition column for those in 2025. Reviewers are key to our society and publications. Our MTT-S Society News features our TC-8 on RF Nanotechnology. This group is involved in many exciting things so have a look at their achievements. And don’t miss the news on the 2025 Asia-Pacific Microwave Conference included in this column instead of the Conference Report column. And talking about the Conference Report column, this issue features MAPCON 2025 that was held in Kochi, Kerala, India. A key point in the issue in what enables the MTT-S and our women in microwaves are key. The Women in Microwaves column covers what happened in September of 2025 at the WESYP Congress at the Hamburg University of Technology. And speaking of young professionals our Young Professionals column covers the student ambassador program and the Student Branches Regional Meeting in Punta Del Este, Uruguay in 2025. Sadly we have another In Memoriam column, this time about Andre Vander Vorst. Please read about all he did for the microwave community and the European microwave association (EuMA).

On the more technical side of this issue we have columns such as MicroBusiness. This month MicroBusiness considers innovation and what voices to listen to. And our Microwave Surfing column laments that our ever more crowded satellite space has created more than just concerns about debris. In our Book Reviews column this month we have a classic: David Pozar’s Microwave Engineering. This book has served many students and professors well. Our society is concerned about its members and our world, as we have heard about in several columns in this issue. We have a new column, Green RF Engineering, which continues the concern about our world. This month you can learn about MTT activities and initiatives in the Green RF Engineering column. Now our New Products column will tell you about more than just the green products but all of them are interesting including such things as new package cooling to the first tri-radio Wi-Fi chip. Finally, our Enigmas, etc. column solves last month’s problem of the kQ of a 6-db attenuator in a 75-Ohm system.

As always, check out the Conference Calendar and attend a conference in person. There is more to life than AI and Zoom meetings.
