An Angularly Stable Triple-band Reflective Polarizing Surface Using a Generative Adversarial Network

Abstract

Linear-to-circular polarization converters with wide- and multi-band capabilities can simplify antenna systems where circular polarization is desired. Multi-band solutions are attractive in satellite communication systems, which commonly have the additional requirement that the sense of polarization is reversed between bands. However, the design of these structures using conventional methods is ad hoc and relies heavily on empirical methods. Here, we employ a data-driven approach integrated with a generative adversarial network to explore the space of polarizer unit cells thoroughly. A triple-band reflective surface with stable performance over incident angles up to and including 30° is proposed.
