Coupled tension-torsion vibration of repetitive beam-like structures [PDF]
, 2006 Equivalent continuum stiffness properties, derived from the eigenanalysis of a single cell of a planar beam-like repetitive structure, have previously been employed within well-known dynamic theories, such as Euler–Bernoulli and Timoshenko for flexural ...

A Novel Analysis of Periodic Structures Based on Loaded Transmission Lines
IEEE Journal of Microwaves, 2023 Periodically loaded transmission lines are characterized by a frequency response with regular pass and stopbands. Interestingly, each of the passbands exhibits a peculiar comb-alike behavior, in which again, nested (or internal) pass and stopbands can be

A practical technique for the generation of highly uniform LIPSS [PDF]
, 2014 Laser-induced periodic surface structures (LIPSS) can be reliably produced with ultrashort (<10 ps) laser pulses given fluence near the ablation threshold. Neat, parallel, uniform structures are harder to reproduce.
