Fast Programming of in‐Plane Hyperbolic Phonon Polariton Optics through Van der Waals Crystals Using the Phase‐Change Material In3SbTe2

Advanced Science, EarlyView.
Launching structures for in‐plane hyperbolic polaritons in α‐MoO3 are optically programmed through already deposited flakes into the phase‐change material In3SbTe2. Precise alignment with the flake's crystal axes, focusing of polaritons by an optically programmed disk, and a first experimental realization toward a nanocavity for in‐plane hyperbolic ...

Multi‐Dimensional Physical‐Layer Security via Digitally Mediated Space–Time Modulation

Advanced Science, EarlyView.
Digitally mediated space–time modulation moves radiation control beyond hardware‐bound switching. Multiple information‐bearing and masking waveforms are jointly synthesized at baseband and coherently coupled to simple periodic time modulation, enabling programmable, independently directed multi‐beam radiation without increasing switching‐state ...

Green's Functions of Non‐Hermitian Systems at Exceptional Deficiency

Advanced Science, EarlyView.
We analyze the responses of a non‐Hermitian lattice system under the condition of exceptional deficiency (ED), when all bands in the system are formed by exceptional points. Using the frequency domain, we identify novel steady‐state responses that root in the broadband super‐Lorentzian Green's function (GF).

Covert Optical Fingerprints Within Overt Structural Colors via Cascaded Cavity Resonances

Advanced Science, EarlyView.
Cascaded photonic–plasmonic cavities combine vivid structural colors with hidden stochastic optical fingerprints in a single monolithic platform. Layered cavities control the overt appearance, while disordered nanogap resonances generate covert scattering with limited mutual influence.

Dual-band dual-circular polarized beam-steering metasurface based on digital coding for intelligent IoV communication

Alexandria Engineering Journal
A novel 1 bit dual-band dual-CP programmable folded metasurface (PFM) with dynamic beam steering capability is proposed for vehicle communications. The proposed PFM consists of a pair of functional metasurface antennas arranged on the top and bottom ...

Architected Spatially Deterministic Multiscale Phase Segregation in Block Copolymer Composites for Augmented Radiative Cooling

Advanced Science, EarlyView.
Multiscale phase segregation in block copolymers enables spatially deterministic structuring from molecular to macroscopic scales, decoupling solar scattering and infrared emission for augmented radiative cooling. ABSTRACT Passive radiative cooling, which reflects solar irradiation while emitting heat through the atmospheric window, provides a ...

Loss‐Engineered Terahertz Pixelated Metasensors for Enhanced Molecular Vibrational Fingerprint Sensing

Advanced Science, EarlyView.
This work presents a THz pixelated metasensor that employs loss optimization and spectral overlap for enhanced molecular vibrational fingerprint sensing. The flexible loss rate tuning through the out‐of‐plane dimension allows the device to operate in the optimal fingerprint enhancement condition.
