Full Asymmetric Radiation Control Through Multi‐Channel Bound States in the Continuum
Bound states in the continuum (BICs) enable extreme light confinement via high Q‐factors, but their radiation splits into half‐spaces with limited beam control. Here, in super wavelength BICs (supporting multiple diffraction orders), we design co‐propagating orders in one half‐space, achieving full tuning of UGRs’ directionality (−1 to 1) and phase (‐π

An Epsilon‐Near‐Zero‐Based Nonlinear Platform for Ultrafast Re‐Writable Holography
We show that an unstructured, sub‐wavelength thick epsilon‐near‐zero material, such as ITO, can be efficiently used for ultrafast re‐writable holography over a broad bandwidth range. We showcase two powerful applications of our scheme, that is, spatial structuring of light and optical computation.

Exploring Routes to Calculating the Effective Magnetic Permeability of Polymer Magnetic Composites
Schematic of a static (undeformed) configuration of the magnetic‐filled polymer network for a semi‐crystalline sample. ABSTRACT Our understanding of the effective magnetic permeability of composite materials composed of randomly dispersed metallic ferromagnetic particles within a nonmagnetic (polymer) matrix must respond to several challenges.

Wood‐based broadband blackbody is achieved by reconfiguration of wood with lignin nanoparticles prior carbonization. Neglectable reflectivity from the visible to infrared wavelengths is obtained by combining thin nanostructures originated from the wood cell walls with long‐range microcavities in the wood lumina.
