Through the use of a static magnetic eld and micro-sized conductive magnetic particles, the MRS can be used to connect separate transmis- sion lines (TL) that operate up to a radio frequency of 5 GHz. The simulated and measured results show the MRS functions well compared to other switching methods. The VEPS's ability to achieve e ective permittivity recon gurability is also demonstrated, showing that the VEPS functions as the well-known mushroom structure when the MRSs are in the on state and as a regular TL when the MRSs are in the o state. Finally, several brief studies of the MRS are performed, including the activation methods, MRS geometry, di erent types of magnetic particles, and smaller embedded MRSs within the VEPS.NDSU Policy 190.6.2https://www.ndsu.edu/fileadmin/policy/190.pdfThesis0000-0002-5872-7400
