Leveraging Metamaterial‐Inspired Wireless Resonator for Reliable Quantitative MRI at 1.5T: Linearity, Bias, and Repeatability Assessment

Advanced Physics Research, EarlyView.
This study designed a nonlinear‐response metamaterial‐inspired wireless resonator (MWR) and systematically evaluated the feasibility of using MWR for quantitative magnetic resonance imaging (qMRI), including T1/T2 mapping, apparent diffusion coefficient, and proton density fat fraction.

On the Impact of Mechanical Constraint on Band Structure and Photo‐Elastic Effect in Photonic Resonators

Advanced Physics Research, EarlyView.
We computationally investigate the mechanical, electronic, and optical properties of strained GeSn microdisks on silicon substrates. By combining photo‐elasticity, strain‐dependent band‐structure calculations, and optical mode analysis, we study how strain distribution, structural configuration, and temperature affect the electronic band structure and ...

Comparative Study of Gas and Liquid Flow in Packed Beds Using Phase‐Contrast MRI

Chemie Ingenieur Technik, EarlyView.
This work presents applications of phase‐contrast magnetic resonance imaging (MRI) to investigate fluid flow fields and temperature in packed beds. Comparison of ethane (C2H6) gas flow with that of water flow is done at similar flow conditions. The temperature of water is also measured using MRI.
