Metamaterial-Based Vibration Mitigation for Enhanced Reliabilityof an Automotive Inverter: A Numerical Study 31 The numerical study presented indicates that LRMs have potential for application in electronic devices to enhance their reliability and lays the groundwork for a possible experimental study of the considered system. Next steps include experimental characterization of the materials usable for stable production processes of the LRM solutions and experimental validation of the proposed solutions via shaker and vehicle testing for the electric drive PEU.
