IEEE Distinguished Lecture Series: Nonresonating Modes: Do It Better!

IEEE AP-MTT Chapter Distinguished Lecturer Dr. Simone Bastioli, RS Microwave Company
Thursday, March 22, 2018, 2:00 pm to 3:00 pm
ElectroScience Laboratory, MRC Conference Room

The innovative concept of nonresonating modes and how this has been recently exploited to extend the performance and capabilities of the state-of-art of microwave filter technology will be presented in this talk. Although the concept is presented by mostly focusing on filters, as these are the components where this new technique has found large application over the past few years, all general features are explained and illustrated in detail thus potentially paving the way for new applications involving other passive microwave components.

Learn about the importance of microwave filters from a system perspective,  the concept of a nonresonating mode, and the benefits of this approach. Explore the concept through a waveguide as well as planar SIW examples, as the rectangular waveguide technology is where these modes were first observed. Most importantly, these examples have been proven to considerably ease the understanding of the concepts from both students and non-experts perspectives.

Walk step-by-step through the general multimode environment of these structures and see several animations that allow you to absorb the more general multimode concept that otherwise often remain an obscure myth for many microwave engineers.

In addition, the presentation extends to the most various filter technologies, such as conventional coaxial structures, dielectric resonators based architectures, as well as more original mixed technologies. The presentation will cover examples of different applications such as three-port junctions for duplexing purposes and will show how well-established four-port components have indeed always “unconsciously” exploited some form of nonresonating modes.

Several manufacturing examples of products developed at RS Microwave will be presented, thus satisfying the more practical taste of an industry audience.


Simone Bastioli (S’10–M’11) received the Ph.D. degree in electronic engineering from the University of Perugia, Italy, in 2010. He is the Acting Chief Engineer at RS Microwave Company Inc., Butler, NJ, United States. Dr. Bastioli is a current IEEE Young Professional (YP), and he was the recipient of the 2012 IEEE Microwave Prize for the invention of TM dual-mode cavities and nonresonating modes.  He is the vice chair of the MTT-8 Filters and Passive Components Technical Committee, and he serves as an Associate Editor of the IEEE Microwave Magazine. In 2008, he was awarded the Best Student Paper Award (First Place) at the IEEE MTT-S International Microwave Symposium (IMS) held in Atlanta, GA, USA, and with the Young Engineers Prize at the European Microwave Conference held in Amsterdam, The Netherlands. In 2009, he was the recipient of the Hal Sobol Travel Grant presented at the IEEE MTT-S IMS held in Boston, MA, USA. He was also awarded the Young Scientist Distinction by the Polish Academy of Science at the 2014 MIKON International Conference held in Gdansk, Poland. His work resulted in several publications in international journals and conferences, as well as several patent applications.
