“From Archimedes Burning Mirror to James Webb Space Telescope: A Journey from the Ancient Past to the Renaissance and the Present”

Abstract: Antennas are the most important engineering devices dealing with the electromagnetic waves in both receive and transmit modes. Among very diverse configurations of antennas perhaps reflector antennas (mirrors) have seen the most unique and exotic applications. They provide the highest gain, widest bandwidth, and best angular resolutions at the lowest costs. The primary role of a reflector antenna (mirror) is to confine or radiate most of the electromagnetic energy including light over its aperture into a focal plane in receive mode or radiate to the far fields for communication or energy transfer in transmit mode. Majority of reflector antennas use classical conic sections, the parabola, ellipse, hyperbola, and sphere, to either focus or efficiently radiate electromagnetic waves at a wide range of frequencies covering low, microwave, mm-wave, THz, optical and beyond. Reflector antennas are typically categorized according to radiation pattern types, reflector surface types, and feed types.
Archimedes is credited with using parabolic reflectors to focus the Sun’s heat on attacking Roman ships in order to set them on fire. At the close of the Renaissance optical mirrors of many kinds resulted in many astronomical discoveries using designs such as Gregorian, Cassegrain and other folded optics configurations. It was not until WWII era that reflector antennas in non-optical regimes received much attention particularly for RADAR applications. Satellite communications including earth observation systems and the current interests in using Cubesats have significantly influenced the developments of exotic designs including offset, shaped, deployable, multi-beam reflector antennas. Many heavenly objects are not only observable in visible light but also emit radiation at radio wavelengths. Apart from observing energetic objects such as pulsars and quasars, radio telescopes are capable of observing other astronomical objects: galaxies, nebulae, black holes, and even radio emissions from planets. The first radio emissions detected by Jansky at Bell Labs in the 1930s were from the Milky Way Galaxy. Inspired by Jansky’s work, in 1937, Grote Reber built the first 9.5-m radio telescope. Since then giant reflector antennas have been built with super resolution capabilities. Most recently we have witnessed the flawless deployment of 6.5m James Webb Space Telescope (JWST) operating primarily at infra-red frequencies. JWST is for sure going to revolutionize our current understanding of the universe addressing the following questions: (a) How did it all start? (b) Are we alone? (c) How is our universe evolving?
In this plenary talk, the development of reflector antennas (mirrors) from Archimedes Burning Mirror (200 BC) to James Webb Space Telescope (2021) is reviewed in a concise and novel fashion. This author was so fascinated by a typical shape of a reflector antenna that when he designed the winning IEEE Antennas and Propagation Society Logo many decades back he used a rendition of a reflector antenna in the logo artwork. His logo design now appears on thousands of publication materials related to the IEEE AP-S publications, symposia flyers and books, etc.

“Huygens’ Metasurfaces for Antenna Beamforming and Beamsteering”

Abstract: We will describe the concept of the Huygens’ metasurfaces which comprise co-located electric and magnetic dipoles forming an electrically dense array of Huygens’ sources or scatterers. These engineered surfaces can be designed to control electromagnetic waves at will. Unlike traditional antenna transmitarrays, Huygens’ metasurfaces can be made sub-wavelength thin and deprived of spurious Floquet modes, while preserving excellent matching characteristics. Huygens’ metasurfaces can be used to manipulate the phase, magnitude and polarization of incident electromagnetic waves, including those from nearby elementary antennas, for a variety of applications. For example, Huygens’ omega bi-anisotropic metasurfaces enable wave refraction at extreme angles without any reflections. We will review progress of such Huygens’ Metasurfaces for antenna beamforming and beamsteering. Examples to be discussed include high aperture efficiency/low-profile antennas, antenna aperture beamforming with simultaneous magnitude and phase control, and electronic beam steering.
