Magnetic particle imaging (MPI) is an emerging molecular technique that relies on the nonlinear magnetization response of superparamagnetic iron oxide nanoparticles. Open-sided MPI (OS-MPI) has attracted considerable interest for its potential to enhance interventional procedures. However, improving spatial resolution OS-MPI poses a significant challenge, mainly due inefficiencies selection coils in generating, rotating, and shifting high-gradient field-free line (FFL). To address this...
Open-sided magnetic particle imaging (OS-MPI) has garnered significant interest due to its potential for interventional applications. However, the system matrix calibration in OS-MPI using sequential scans is a time-consuming task and susceptible low signal-to-noise ratio (SNR) resulting from small sample size. These challenges have hindered practical implementation of matrix-based reconstruction sequentially scanned OS-MPI. To address these issues, we propose novel method, named scan-based...
In this work, we propose an active spoof magnetic localized surface plasmonic metamaterial that can realize the dynamic control of electric and resonances in ultrathin corrugated metallic spiral disk. Active component varactor has been loaded into such disk structure. By changing supplied voltages devices, resonant frequencies electric- magnetic-dipole be dynamically tuned, thereby flexibly controlling multipole interference resonances. Experimental results are good agreement with simulated ones.
In this paper, we propose a high gain and low RCS Huygens' metasurface lens(meta-lens) antenna, which is composed of combination horn antenna Huygens metasurface. The consists two same metallic structures that are antisymmetrically etched on the upper lower sides F4B dielectric substrate. Compared with multilayer frequency selective surface, proposed can provide larger transmission phase-shift range be used to realize thin high-performance focusing meta-lens in broadband.
