MXene‐Coated 3D Printed Horn Antennas for Ku Frequency Band

open access: yesAdvanced Materials Technologies, EarlyView.
An additive manufacturing approach to 3D printing horn antennas and coating them with Ti3C2Tx MXene is proposed. Rapid fabrication of lightweight, high‐performance antennas operating in the Ku‐band (12.4–18 GHz) has been demonstrated. The MXene‐coated antennas exhibit comparable electromagnetic performance to conventional, costly aluminum ones, with ...

Terahertz Chiral Metamaterials Enabling Broadband Polarization Conversion Using Polarization Guiding Effect

open access: yesAdvanced Materials Technologies, EarlyView.
A broadband terahertz polarization rotator consisting of twistingly stacked silicon–air metagratings is designed based on the polarization guiding effect and experimentally shown to achieve 90° linear polarization rotation for both TE and TM incidences.

Two‐Photon Polymerized Microvascular Environments for Multicellular Modeling of the Blood–Brain Tumor Barrier

open access: yesAdvanced Materials Technologies, EarlyView.
Modeling the blood–brain tumor barrier is challenging due to complex interactions between brain microvasculature and glioma cells. We present two‐photon polymerized 3D micro‐porous capillary‐like structures that support endothelial alignment, cytoskeletal organization, and pericyte‐endothelial‐glioma tri‐cultures.

Enhancing Organic Light‐Emitting Diode Performance Using Naturally Derived Diatomite: A Cost‐Effective and Eco‐Friendly Strategy

open access: yesAdvanced Optical Materials, EarlyView.
Diatomite‐based light extraction structures enable enhanced photon outcoupling through multi‐angle scattering and far‐field redistribution. By harnessing the unique scattering behavior of diatomite, this approach introduces randomly oriented scattering centers that effectively reshape internal light propagation.

Phase Topology Stability of an Optical Vortex via an Electrically Controlled Twist‐Planar Oriented Liquid Crystal Fresnel Lens

open access: yesAdvanced Optical Materials, EarlyView.
A simple and efficient method for determining the stability of optical vortices via Fourier transform using a conventional spherical lens is presented. The theoretical and experimental results demonstrate a practical approach to directly and unambiguously measure the magnitude and sign of the topological charge of a beam without altering an ...
