Reflectarray Antennas: Theory, Designs, and Applications
In recent years, reflectarrays have emerged as the new generation of high-gain antennas, which have attracted increasing interest in the antenna community because of their low-profile, low-mass, and low-cost features. The reflectarray antenna is a hybrid design, which combines the many favorable features of reflectors and printed arrays and offers many notable advantages over these two classic high-gain antennas. The aim of this seminar is to present a comprehensive overview of the reflectarray design and state-of-the-art technology. It will enable attendees to understand the basics of reflectarray systems, become familiar with reflectarray analysis techniques and enabling technologies, and apply this knowledge to designing reflectarrays for diversified applications.
Surface Electromagnetics: From Electromagnetic Band Gap to Metasurface and Beyond
From frequency selective surfaces to electromagnetic band-gap (EBG) ground planes, from impedance boundaries to Huygens metasurfaces, novel electromagnetic surfaces have been emerging in both microwaves and optics. Many intriguing phenomena occur on these surfaces, and novel devices and applications have been proposed accordingly, which have created an exciting paradigm in electromagnetics, so-called surface electromagnetics. This seminar will review the development of electromagnetic surfaces as well as the state-of-the-art concepts and designs. Detailed presentations will be provided on the unique electromagnetic features of EBG ground planes and advanced digital surfaces. Furthermore, a wealth of antenna examples will be presented to illustrate promising applications of surface electromagnetics in antenna engineering.
