Glide-Symmetric Acoustic Waveguides for Extreme Sensing and Isolation
Nikolina Janković, Andrea Alù
Glide symmetry offers new degrees of freedom to engineer the properties of periodic structures, and thus it has been exploited in various electromagnetic structures. However, so fa…
Atomic-Scale Defect Detection by Nonlinear Light Scattering and Localization
Farbod Shafiei, Tommaso Orzali, Alexey Vert +6
Hetero-epitaxial crystalline films underlie many electronic and optical technologies but are prone to forming defects at their hetero-interfaces. Atomic-scale defects such as threa…
Wood Anomalies and Surface-Wave Excitation with a Time-Grating
Emanuele Galiffi, Yao-Ting Wang, Zhen Lim +3
In order to confine waves beyond the diffraction limit, advances in fabrication techniques have enabled subwavelength structuring of matter, achieving near-field control of light a…
