Design and Fabrication of High Dielectric GRIN Lens for a Directive Antenna Using a Hybrid Filled Voxel Additive Manufacturing Technique

open access: yesAdvanced Materials Technologies, EarlyView.
Hybrid‐filled voxel AM enables integration of high‐permittivity materials into additively manufactured devices. Using this approach, a graded refractive index (GRIN) lens is demonstrated, achieving a 50% antenna size reduction with enhanced directivity.

Dual‐Emission Switching in a Mn(II)‐Based Hybrid Bromide via Water Coordination: Synthesis, Structure, and Processing

open access: yesAdvanced Optical Materials, EarlyView.
This study reports the synthesis, structure, and optical properties of (pr‐ted)2[MnBr4], a luminescent manganese (II) hybrid halide. It shows green emission under UV and transforms into a red‐emitting hydrated phase with humidity, reversible by heat or vacuum. Structural, photophysical, and theoretical analyses confirm the mechanism.

Terahertz Waveform‐Selective Antenna Using a Patch Structure Loaded with Nonlinear Circuits

open access: yesAdvanced Photonics Research, EarlyView.
A waveform‐selective antenna that integrates the functions of waveform selectivity, electromagnetic shielding, and EM wave radiation has been proposed. By integrating different nonlinear circuits and selecting appropriate component values, the antenna can achieve high reflection of either a pulse wave or a continuous wave, while allowing the other ...
