    Flexible and wireless metasurface coils for knee and elbow MRI by Daniel M. Düx, Robert Kowal, Lucas Knull, Simon Schröer, Othmar Belker, Dominik Horstmann, Moritz Gutt, Holger Maune, Oliver Speck, Frank Wacker, Bennet Hensen, Marcel Gutberlet

    Published 2025-01-01
    “…In knee MRI, the MC + spine coil provided higher SNR compared to the flex coil, except posterior (superficial-anterior: +69%, p = 0.008; middle: +288%, p = 0.008; deep-posterior: −12%, p = 0.148) versus the knee coil, the MC + spine coil was superior in the middle but non-different in superficial pre-patellar areas and less in deep-posterior areas (superficial-anterior: −8%, p = 0.188; middle: +44%, p = 0.008; deep-posterior: −36%, p = 0.016). Conclusion Wireless MCs exhibited great potential for knee and elbow MRI outperforming the flex coil. …”

    Path Loss Modeling of Wireless Signals in Underground Tunnels by Yaning Li, Baoguo Yu, Lu Huang

    Published 2025-01-01
    “…Typical features of underground tunnels (sidewall roughness, metal conductors, tunnel inclinations, etc.) significantly affect signal propagation, making it difficult for a single modeling approach to accurately describe the field strength attenuation of a wireless channel in an underground tunnel. In this paper, a hybrid model describing the propagation attenuation of wireless signals in underground tunnels is proposed, which divides the propagation channel into three subdomains according to the length of the tunnel, namely, the region of the free space propagation model, the region of the multimode propagation described by the ray tracing method, and the region of the improved waveguide model by adding the influences of tunnel roughness, tunnel inclination, and metal pipes. …”
