Reconfigurable Geometric Phase Matching by Multilayered Nonlinear Thin‐Film Crystals
The concept of geometric phase matching is demonstrated as a dynamically reconfigurable approach for tunable nonlinear wave mixing in multilayered nonlinear thin‐film crystals. Experimental results reveal full modulation in a bilayer structure and near‐perfect spin‐selective phase matching of second‐harmonic generation in an eight‐layer configuration ...

Wavefront Shaping for Optimal Extinction of Focused Light by Individual Nanoscatterers
Wavefront shaping enables near‐complete optical extinction by nanoscatterers separated from a planar reflector. Time‐reversed emission profiles provide optimal illumination conditions, yielding 70% extinction from a single plasmonic nanoparticle and up to 90% from sub‐wavelength nanoparticle clusters, offering a promising route to efficient in‐ and out‐

Temporal interfaces are abrupt refractive index changes used in time‐varying optics, but also transitions to nonequilibrium states. This work explores the inelastic scattering of time‐varying light by nonthermal acoustic phonons in the vicinity of temporal interfaces.

Ultimate Intrinsic SNR Depends on B0 Orientation
ABSTRACT Purpose This work aims to investigate the effect of B0$$ {B}_0 $$ orientation on the uiSNR in MRI. Methods Electromagnetic simulations were performed on both realistic body models and simplified geometric models. Comparisons between (1) opposite B0$$ {B}_0 $$ directions along the head‐foot (HF) axis, corresponding to head‐first and feet‐first ...

Design of an In Vivo‐Like Phantom for Quantitative Body CEST MRI
ABSTRACT Purpose To design and validate a reproducible in vivo‐like fat‐containing CEST phantom that enables robust quantitative CEST MRI for body applications by providing physiologically realistic relaxation properties, relevant endogenous CEST contrasts (amide, guanidino, rNOE, and semi‐solid MT), and a controlled fat component.
