Inverse Design of a Wide-Angle Wideband Programmable THz Reflectarray Through Generative Adversarial Networks [PDF]
International Journal of Information and Communication Technology ResearchA reflectarray optimized through a Generative Adversarial Network (GAN) is demonstrated. This design focuses on the impact of the top layer on the reflection phase and utilizes the correlation between phase distribution and the direction of the reflected

Nonreciprocal Wavefront Engineering with Time-Modulated Gradient Metasurfaces [PDF]
, 2019 We propose a paradigm to realize nonreciprocal wavefront engineering using time-modulated gradient metasurfaces. The essential building block of these surfaces is a subwavelength unit cell whose reflection coefficient oscillates at low frequency.
