STEM‐EELS and full‐wave FDTD reveal electron‐driven surface‐polariton modes at buried Au/oxide/Si interfaces with 10 nm SiO2 or Al2O3 spacers. Extinction is dominated by non‐radiative absorption, while oxide permittivity shifts the resonance and controls evanescent‐field penetration across the spacer into silicon.

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Nonresonant Magnetic Flux Control Enabling Low‐Loss Epsilon‐Near‐Zero Cavity Antennas
Can photonic doping be achieved without resonance? A passive metallic inclusion is shown to engineer effective permeability in epsilon‐near‐zero cavity antennas through magnetic‐flux exclusion, reproducing the response of resonant photonic dopants while reducing losses and providing a unified perspective on photonic doping.

Design of a Low-SLL SIW Slot Array Antenna With a Large Declination in
A small-size large-declination longitudinal slot array antenna based on substrate integrated waveguide (SIW) technology was proposed. Compared with the conventional SIW slot array, the proposed antenna achieves a larger declination and a lower SLL.
