Measuring with strain gages has a limitation of consuming time to prepare for the experiment and attaching near the MLCCs, making it does not represent the physical quantities of the MLCCs itself. In this study, we propose a ‘failure criteria for a

Electromagnetic properties of radar absorbing structures (RASs) are highly affected by their curvatures. Therefore, novel full-field curvature compensation methods in the reflection loss evaluation of curved RASs are proposed. These methods are commo
