Advanced Optical Materials, EarlyView.A maskless, SLM‐driven approach enables the deterministic inscription of arbitrary topographical features in azopolymer films by mapping complex vectorial light fields onto local viscoplastic stress. This platform allows for the rapid generation and dynamic erasure of high‐aspect‐ratio micro‐spikes, offering a versatile tool for reconfigurable flat ...

Coherent Absorption Reveals Colors Hidden in a Grey Fabry–Pérot Cavity
Advanced Optical Materials, EarlyView.A dielectric thin film shows colors depending on its thickness; this effect can be used to encode information normally accessible through single‐beam spectroscopy. We developed a method to conceal this kind of information, based on coating the dielectric with a matched conductor, that suppresses the color‐bearing thin‐film resonances.

ON A GENERALIZATION OF CLOSE-TO-CONVEXITY OF COMPLEX ORDER
Tamkang Journal of Mathematics, 1998 The class $V_k$ of bounded boundary rotation is used to generalize the concept of close-to-convexity of complex order. A function $f:f(z)=z+\sum_{n=2}^\infty a_nz^n$, analytic in the unit disc $E$, belongs to $T_k(b)$, $b \neq 0$ (complex) if and only if there exists a function $g \in V_k$ such that \[ Re\left\{1+\frac{1}{b}\left(\frac{f'(z)}{g'(z)}

Micromachined Double‐Membrane Mechanically Tunable Metamaterial for Thermal Infrared Filtering
Advanced Photonics Research, Volume 6, Issue 5, May 2025.Herein, a mechanically tunable double‐layer plasmonic metamaterial leveraging the extraordinary optical transmission effect observed in subwavelength arrays of openings within thin metal layers is presented. The concept is experimentally validated by integrating the proposed metamaterial structure into an electrostatic parallel‐plate actuator to create

Close-to-convex multivalent functions with respect to weakly starlike functions
, 1972 It is the object of this article to define close-to-convex multivalent functions in terms of weakly starlike multivalent functions. Six classes are defined, and shown to be equal.

Advanced Robotics Research, EarlyView.Pak Biawak, a necrobot, embodies an unusual fusion of biology and robotics. Designed to repurpose natural structures after death, it challenges conventional boundaries between nature and engineering. Its movements are precise yet unsettling, raising questions about sustainability, ethics, and the untapped potential of biointegrated machines.
