Transformation Optics and Its Applications to Lens Antennas
August 13, 2021 @ 4:00 am - 5:00 am
IEEE AP-S DL Talk Co-Sponsored by IEEE Hong Kong & IEEE North Jersey AP/MTT Chapter
Abstract
Optical transformation can be used to link one coordinate system of one space to any other while retaining the same electromagnetic propagation behavior of the original. The outcome of such a transformation is the necessity to fill the space with a material with both magnetic and dielectric properties.
There are several routes to take when employing transformation optics, and three of these are non-Euclidean, analytical, and quasi-conformal transformation. Non-Euclidean transformations produce full dielectric materials, and it is very promising for surface wave applications, particularly for antennas on vehicles. The analytical transformation results in the necessity of anisotropic materials in the implementation of designs. The difficulties of the latter can be solved with the quasi-conformal technique, which allows the design of full dielectric and isotropic configurations at the price of assuming an approximation of the conformal anisotropy.
In this seminar, Oscar Quevedo-Teruel will explain the fundamentals of transformation optics, the different types of transformations, emphasizing their advantages and disadvantages, and their potential use for lens antennas, such as hyperbolic lenses and Luneburg lenses that have received recent interest for Satellite and 5G communications.
