Broadband high-contrast-grating-type waveplates for the terahertz range

Surya Revanth Ayyagari, Andreas K Klein, Simonas Indrišiūnas, Vytautas Janonis, Daniil Pashnev, Abdu Subahan Mohammed, Guillaume Ducournau, Andreas Stöhr, Irmantas Kašalynas

The high-contrast-grating waveplates utilizing high contrast between silicon and air refractive indexes were developed in order to perform as a quarter wave and a half wave plate in the selected THz frequency range. The waveplates possessed anti-reflective properties due to the specific inclination…

Single-Channel Imaging at Low Sampling Rates

Salah Skitioui, Cyril Decroze, Ettien Kpre, Christophe Gaquière, Okan Yurduseven, Thomas Fromenteze

This study introduces a method for single-channel imaging at low sampling rates, utilizing Frequency-Modulated Continuous Wave radar combined with space-frequency multiplexing. This approach significantly reduces system complexity and data acquisition demands by encoding scene reflectivity into a…
