Wave Scattering at temporal interfaces with spatial-translation-symmetry mismatch
Cong Chen, Kaijun Yi, Guoliang Huang +1
Temporal interfaces enable wave manipulation through broken time-translation symmetry, but conventional formulations generally assume that spatial-translation symmetry is preserved…

Resonance-induced frequency splitting and evanescent modes at temporal interfaces in elastic metamaterials
Cong Chen, Kaijun Yi, Gengkai Hu
Temporal interfaces, defined by abrupt changes in material properties, break temporal translational symmetry and enable wave phenomena fundamentally different from those at spatial…
