... together with the displacement of the UCs at points , , and of the dispersion curves. Since both UC models represent the same infinite periodic structure, the corresponding dispersion curves and modeshapes are as good as identical (relative error of 10 −7 ). The mode on point represents an axial mode...

... and frequency/wavenumber, provides strong evidence that transient resonant capture is the driving force behind the global breaking of reciprocity in the periodic structure. In a companion work, some of the theoretical results presented herein are experimentally validated with a lattice composed of two-scale...

Instead of considering the dynamics of a single substructure alone, an essentially different technique named as wavenumber-harmonic method for the analysis of periodic structures is presented. The method involves the use of Fourier transform, then the associated wavenumber response...
