In this study, the feasibility of using Lamb waves in functionally graded (FG) nano copper layered wafers nondestructive evaluation is evaluated. The elastic parameters and mass densities these vary with thickness due to variation grain size. power series technique used solve governing equations variable coefficients. To analyze multilayered structures, which material are continuous but underiv...

Multilayered fibre–metal laminates (FMLs) are composed of metal semifinished products and fibre-reinforced plastics, benefit from the advantages both material classes. Light metals in combination with thermoplastics highly suitable for mass production lightweight structures good mechanical properties. As formability light sheets is sometimes limited at room temperature, increasing process tempe...

The electromagnetic wave interaction with layered structures constitutes a crucial topic of current interest in theoretical and experimental research. Generally speaking, several modelling and design problems, encountered, for instance, in SAR (Synthetic Aperture Radar) application, GPR (Ground Penetrating Radar) sensing, radar altimeter for planetary exploration, microstrip antennas and MMICs ...
