講演2(Distinguished Microwave Lecturer 講演)
・タイトル:Nonresonating Modes Do It Better!
・講師: Dr. Simone Bastioli (RS Microwave Company Inc., USA)
・概要: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. After a brief discussion highlighting the importance
of microwave filters from a system perspective, the main concept of the talk will be
introduced by defining what is a nonresonating mode and by illustrating what are the
benefits of this approach. The concept is then gradually explained by using some 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 proved to considerably
ease the understanding of the concepts from both students and non-experts perspectives.
The general multimode environment of these structures is described step-by-step and several
animations are introduced during the explanation thus really allowing the audience to absorb
the more general multimode concept that otherwise often remain an obscure myth for many
microwave engineers. The presentation is then extended 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 also cover few examples regarding
different applications such as three-port junctions for duplexing purposes, and showing how
actually some well-established four-port components have indeed always “unconsciously” exploited
some form of nonresonating modes. Several manufacturing examples of actual products developed
at RS Microwave (Dr Bastioli‘s affiliation) are going to be presented along this talk, thus
also satisfying the more practical taste of an industry audience.
