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

Advanced 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.

Wireless Power Transfer Modalities for Implantable Bioelectronics: Electromagnetic, Acoustic, and Magneto‐Dynamic Perspectives

Advanced Materials Technologies, EarlyView.
This review traces the evolution of wireless power transfer (WPT) for implantable medical devices, spanning electromagnetic, magnetoelectric, acoustic, and magneto‐dynamic systems. Quantitative comparisons of power, distance, and device scale highlight trade‐offs across modalities, while emerging hybrid mechanisms reveal strategies to overcome ...

Engineering Spontaneous Orientation Polarization in Blends of Polar Organic Semiconductors

Advanced Optical Materials, EarlyView.
Spontaneous orientation polarization (SOP) in organic semiconductor thin films can be modulated through molecular blending. A nonpolar dopant disrupts anti‐parallel dipole alignment in a polar host, promoting enhanced dipole orientation. Meanwhile, polar‐polar blends can retain their original dipole alignment, resulting in a linear GSP slope trend ...

Inverse Design in Nanophotonics via Representation Learning

Advanced Optical Materials, EarlyView.
This review frames machine learning (ML) in nanophotonics through a classification based on where ML is applied. We categorize methods as either output‐side, which create differentiable surrogates for solving Maxwell's partial differential equations (PDEs), or input‐side, which learn compact representations of device geometry.

Plasmonic Metasurfaces with Structural Chirality and Pseudo‐Chirality for Enhanced Circular Dichroism and Enantiomeric Recognition

Advanced Optical Materials, EarlyView.
A planar plasmonic metasurface composed of asymmetric gold nanostructures is shown to exhibit both anisotropic and chiral/pseudo‐chiral optical responses. By tailoring the polarization and angle of incidence, the metasurface significantly enhances optical chirality and enables enantiospecific detection.
