Unlocking Terahertz Steganography: Authentication of Hidden Images in Flexible Media
Advanced Materials Technologies, EarlyView.Hidden information in multilayered devices, such as steganographic portraits, is detected and authenticated using reflection‐mode terahertz time‐domain imaging. Image reconstruction relies on a dedicated figure‐of‐merit obtained by integrating the signal intensity over the time‐window associated with the reflection from the metallic mirror backing the ...

Advanced Optical Materials, EarlyView.Comparing Fabry–Perot and plasmonic nanorod cavities reveals how the number of dark states dictates polariton relaxation. The high number of dark states results in a polaritonic bottleneck, while reducing the number of dark states enables to measure the polaritonic decay.

Two‐Dimensional Isotropic Spatial Differentiation Through Complete Polarization Control
Advanced Optical Materials, EarlyView.This work enables two‐dimensional isotropic spatial differentiation at planar interfaces over a wide range of incident angles by extending the output polarization from linear to elliptical. The choice of incident angle can be used to balance broader spectral response at low angles and higher edge‐detection efficiency at larger angles.
