A symmetry-related interface state propagates along a surface and shapes an emitted acoustic field.
A designed interface combines increased group velocity with a wider bandgap and confined propagation.
Membranes, microperforations and coiled resonators are optimized before cells are rearranged into a vented supercell.
Engineered electronic transitions and guided-mode fields enable free-space excitation of second-harmonic generation.
A stiff network and a compliant phase redirect internal strain toward energy-dissipating deformation.
Curved chains, crosslinks and alignment translate selected polymer-network mechanisms into printed structures.
Field-aligned composite layers realize a conductivity design tested under several heat-source arrangements.
Stiff PLA members and compliant TPU links produce a programmed sequence of deformation and force peaks.
Ultrafast modulation and an exceptional-point transition produce gain that offsets part of the plasmonic loss.
