Frequency‐Selective Terahertz Wave Amplification by a Time Boundary in Huygens' Metasurface

open access: yesAdvanced Optical Materials, EarlyView.
In a free‐standing all‐dielectric Huygens' metasurface, ultrafast pulsed laser excitation is used to establish the time boundary for a coherent modulation to the electric and magnetic polarizability in the adiabatic limit. Amplification of THz waves at frequencies that can be continuously tuned have been achieved, showing an effective energy gain up to

Simultaneous Perfect Anomalous Reflection and Angle of Arrival Sensing in Reconfigurable Intelligent Surfaces

open access: yesAdvanced Optical Materials, EarlyView.
A reconfigurable intelligent surface is proposed that can simultaneously anomalously reflect the light and sense the angle of arrival. An in situ optimization of either the currents flowing on array elements or the far field in the receiver direction realizes anomalous reflection and suppresses parasitic scattering.
