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.

Hydrophobic 1D and 3D Anodic Alumina Radiative Coolers on Aluminum: Humidity‐Resilient Daytime Sub‐Ambient Cooling

Advanced Optical Materials, EarlyView.
1D and 3D nanoporous anodic aluminum oxide (AAO) surfaces were functionalized with stearic acid (STA) to increase hydrophobicity and reduce the influence of humidity on radiative cooling performance. The STA coating improves cooling behavior under humid atmospheric conditions (Madrid summer), before while keeping the optical properties required for ...

On the geometric sequences of reflection coefficients

IEEE Transactions on Acoustics, Speech, and Signal Processing, 1990
It is shown that a decaying geometric sequence of reflection coefficients corresponds to a predictor polynomial that has all of its roots on a circle centered at the origin of the complex z plane. It is shown that the radius of this circle is equal to the magnitude of the ratio of any two consecutive terms in the geometric sequence. >
