In recent years, metasurfaces have shown extremely powerful abilities for manipulation of electromagnetic waves. However, the local response conventional yields an intrinsic performance limitation in terms efficiency, minimizing their implementation real-life applications. The efficiency reconfigurable further decreases because high density meta-atoms, reaching 74 meta-atoms per ?2 area, incorp...

In this study, the seismic response of a container crane under near-field and far-field ground motions was investigated using shaking table test on 1/20 scale crane. The designed fabricated based similitude laws, in which three independent quantities: geometric length, acceleration, elastic modulus, were used to design A series tests conducted at Seismic Research Test Center, Pusan National Uni...

Abstract Coherent emission coming from relativistic charged bunches is of great interest in a wide range user-oriented applications and high-resolution diagnostics. The complete characterization such therefore important view understanding its potential. Here we present temporally-resolved the radiation emitted by ultra-short electron using temporal diagnostic based on electro-optical sampling w...
