A Look at the September Issue [From the Editor’s Desk]

IEEE Microwaves Magazine -

Each Society within IEEE covers a specific area of electrical engineering, defined in the Society’s field of interest (FOI) statement. For the IEEE Microwave Theory and Technology Society (MTT-S), the FOI statement reads, “The field of interest of the society shall be theory, techniques and applications of guided wave and wireless technologies spanning the electromagnetic spectrum from RF/microwave through millimeter-waves and terahertz, including the aspects of materials, components, devices, circuits, modules, and systems which involve the generation, modulation, demodulation, control, transmission, sensing and effects of electromagnetic signals” [1]. Note that the FOI statement is quite broad—and intentionally so because our field is also quite broad, covering passive and active components, circuits, and systems in a variety of applications, thus making the MTT-S the “MHz to THz community.” This broad technology space is represented and fostered by our 28 technical committees in core technologies and techniques as well as systems and applications [2]. This idea of breadth within our Society is this month’s theme for IEEE Microwave Magazine: “Breadth of MTT.” In this issue, we offer you four technical articles that are examples of the wide technological reach of our community, as well as the usual columns that you expect.

What Have We Done? [MicroBusiness]

Frequent readers of this column may recall that I am fortunate to be the grandfather of the most adorable grandchild ever [1]. At this writing, he is almost 16 months old and still most adorable. He is also, unsurprisingly, the cleverest 16 month old ever.

The Search for Extraterrestrial Intelligence 2024 [Microwave Surfing]

IEEE Microwaves Magazine -

Regular readers of the column will recall my long-standing fascination with the scientific search for extraterrestrial intelligence (SETI). Last year, I wrote about the American astrophysicist Frank Drake (1930–2022), who kickstarted SETI in 1960 with his Project Ozma [2] and whose eponymous Drake equation [3] has been used to estimate the number of observable civilizations in our galaxy. Recently, I browsed through a new crop of books devoted to SETI. They included Interstellar: The Search for Extraterrestrial Life and Our Future in the Stars [1] by the Harvard astronomer Avi Loeb; Alien Earths [4] by Lisa Kaltenegger, the director of the Carl Sagan Institute at Cornell; and The Little Book of Aliens [5] by the physicist Adam Frank of the University of Rochester. Even a cursory perusal of these books makes one thing very clear. Not only are scientists going beyond Drake’s original vision of searching for “radio waves sent forth by other intelligent civilizations” [2], but the current SETI discourse also employs many terms unfamiliar to the wider public. Here are a few of them to bring you up to speed.

Close-In Dynamic Range Considerations in Upconverted and Frequency-Multiplied Frequency-Modulated Continuous-Wave Radars at Ku-Band: Close-In Dynamic Range Considerations in FMCW Radars

IEEE Microwaves Magazine -

As silicon radars have become commonplace at microwave and millimeter-wave frequencies driven by automotive and other sensing applications, two specific architectures for these radars have become dominant in the literature: frequency-multiplied radar systems [1], [2], [3], [4], [5], [6], [7], [8] and upconverted radar systems [9], [10]. While both architectures are well reported, the literature in microwave theory and technology thus far does not offer a robust quantitative comparison of the two approaches regarding their radar behavior, especially in the case of dynamic range.
