Energy Focusing Metasurface Based Wireless Power Transfer System for Compact Unmanned Mobilities

open access: yesAdvanced Optical Materials, EarlyView.
A miniaturized wireless power transfer system integrates a metasurface lens, microstrip patch antenna, and RF‐CMOS rectifier to enhance mmWave reception efficiency and reduce size. Leveraging mmWave short wavelengths, it achieves high gain on small platforms. The system's polarization independence and wide‐angle reception ensure robust performance.

Hyperphosphorescent OLEDs: Harnessing the Power of MR‐TADF Terminal Emitters

open access: yesAdvanced Optical Materials, EarlyView.
Hyperphosphorescent organic light‐emitting diodes (HP‐OLEDs) use phosphorescent sensitizers with multiresonant thermally activated delayed fluorescence terminal emitters. HP‐OLEDs show efficient, narrowband electroluminescence and moderate efficiency roll‐off.

Topology Optimization Enables Freeform Matrix Fourier Optics

open access: yesAdvanced Optical Materials, EarlyView.
A topology‐optimized freeform metasurface is designed and fabricated to realize matrix Fourier optics, enabling the diffraction of multiple polarization states into distinct far‐field orders. By combining forward design with gradient‐based inverse optimization, high polarization contrast of up to 98.7% is achieved.
