Radio-Frequency Actuated Polymer-Based Phononic Meta-Materials for Control of Ultrasonic Waves (open access)

Radio-Frequency Actuated Polymer-Based Phononic Meta-Materials for Control of Ultrasonic Waves

This article describes the achievement of radio-frequency control of a n ultrasonic phononic crystal by encapsulating it in a composite of high k-10% KF-doped BaTiO₃ dielectric nanoparticles with poly(N-isopropylacrylamide) (PNIP Am)-based hydrogel.

ALMA Observations Show Major Mergers Among the Host Galaxies of Fast-growing, High-redshift, Supermassive Black Holes (open access)

ALMA Observations Show Major Mergers Among the Host Galaxies of Fast-growing, High-redshift, Supermassive Black Holes

This article presents new ALMA band-7 data for a sample of six luminous quasars at z ≃ 4.8, powered by fast-growing supermassive black holes (SMBHs) with rather uniform properties.

Coupling of Surface Plasmon Polariton in Al-Doped ZnO with Fabry-Pérot Resonance for Total Light Absorption (open access)

Coupling of Surface Plasmon Polariton in Al-Doped ZnO with Fabry-Pérot Resonance for Total Light Absorption

This article presents finite-difference time-domain (FDTD) simulations on total light absorption (TLA) resulting from the coupling of a surface plasmon polariton (SPP) with Fabry-Pérot (F-P) resonance in a three-layer structure consisting of an AZO square lattice hole array, a spacer, and a layer of silver.
