Webb6 apr. 2024 · ABSTRACT. A metasurface absorber based on the slow-wave effect has the advantages of long interaction time and high absorption. A slow-wave metasurface absorber is constructed using the periodic arrangement of the Jerusalem cross, which achieves a reflectivity of −15.0 dB at 5.0 GHz. Furthermore, dual-frequency absorption is … Webb12 mars 2024 · Die Peristaltik des Darmes wird durch langsame Potenzialwellen (E slow waves), ausgehend von sog.
