Structured coherent thermal emission from non-Hermitian metasurfaces [PDF]

Nature Communications
Metasurfaces can reshape thermal radiation with tailored directionality, spectral selectivity and polarization control, yet coherent thermal emission exhibiting vectorial polarization or structured light property has been rarely demonstrated.

Optical trapping and fluorescence control with vectorial structured light

Scientific Reports, 2022
Here we functionalized micro-scaled polymer beads with nano-scaled quantum dots and demonstrate optical trapping and tweezing, with in-situ fluorescence measurement, in an all-digital all-optical configuration.

Entanglement-controlled vectorial meta-holography. [PDF]

Light Sci Appl
Abstract Metasurfaces can precisely manipulate the amplitude, phase, and polarization of incident light through subwavelength structures, greatly advancing the quantum meta-holographic imaging. However, the current methods of using quantum holography only control either the amplitude or the phase on the imaging plane, so the resulted ...

Stress-driven photo-reconfiguration of surface microstructures via vectorial field-guided lithography [PDF]

Light: Science & Applications
Pattern formation driven by mechanical stress plays a fundamental role in shaping structural organization in both natural and human-made systems. Using light as a vectorial stimulus may offer a powerful route to control stress-induced pattern formation ...

Control vectorial de motores de inducción

Visión Electrónica, 2010
La técnica de SVPWM (modulación por ancho de pulso del vector espacio) permite mejorar la respuesta dinámica de un motor de inducción, caracterizado por su robustez, costo y sencillez. Sin embargo, su uso ha sido restringido por las sobreintensidades que

Continuous polarization–wavelength mapping with nonlocal metasurfaces [PDF]

Light: Science & Applications
Simultaneous and continuous control over polarization and wavelength—two orthogonal and information-rich degrees of freedom—remains a central challenge in metasurface photonics, long hindered by intrinsic dispersion constraints and structural degeneracy.

The urban Triatoma infestans challenge: integrative insights for vector control and Chagas prevention policies in San Juan, Argentina [PDF]

Parasites & Vectors
Background Chagas disease has historically been linked to triatomines and rural areas. However, urban infestations by one of its vectors, Triatoma infestans, are increasingly being reported.

The vectorial control of magnetization by light [PDF]

Nature Communications, 2011
Coherent light-matter interactions have recently extended their applications to the ultrafast control of magnetization in solids. An important but unrealized technique is the manipulation of magnetization vector motion to make it follow an arbitrarily designed multi-dimensional trajectory.
