Beamforming capabilities are required by the wireless communication networks of the future. Beamforming networks (BFNs), such as the Butler matrix or Rotman lens, are necessary for these circumstances to direct the beam in different directions. But creating such BFNs is not easy. These networks demand the user to be well-versed in computer-aided design technologies in addition to sophisticated mathematical formulas for creating such BFNs. We have been working on creating GUI-based software to handle the construction of such designs. Without having to worry about the underlying physics of the design, such software gives the user a number of options for fine-tuning the design of such networks. In this way, it is simple to import the BFN produced by the software into modern simulators and modify it as necessary. The presentation will summarize the key takeaways from our extensive experience developing software of this type for electromagnetic applications.

Periodic structures play a fundamental role in the field of electromagnetics, providing unique and versatile ways to manipulate electromagnetic waves. These structures are characterized by their repeating patterns, which give rise to various intriguing phenomena and properties. Periodic structures enable the control of wave propagation by guiding and redirecting electromagnetic energy and manipulating its polarization and phase. They find applications in diverse fields, including antenna design, and photonics. The study and utilization of periodic structures have opened up new frontiers in electromagnetics, paving the way for innovative devices and technologies with enhanced performance and functionality. In the past, we used periodic structures for design on reflectarray, transmitarray, superstrate, and lens designs. The presentation will summarize the key takeaways from our experience developing electromagnetic designs using periodic structures.
