Hybrid modes of the passive-core corrugated-waveguide laser

Canadian Journal of Physics, 1976
Coupled-mode theory is employed to obtain the threshold gains for oscillation on hybrid modes of a passive-core corrugated-waveguide laser pumped in a central portion of its length. Methods are developed for calculating intermode coupling coefficients and loss coefficients resulting from diffraction into any order of waveguide corrugations of ...

Dynamic Compressive Response of Sinusoidal Corrugated Core Sandwich Plates

International Journal of Applied Mechanics, 2018
In this paper, the dynamic compressive response of metal sinusoidal corrugated core sandwich plates is investigated. The analytical model for the reaction forces of top and bottom face sheets subjected to constant velocity are developed. Finite element (FE) method is carried out to predict the dynamic collapse of metal sinusoidal corrugated cores ...

Compression Capacity of Corrugated Core Hybrid Composite Sandwich Structure

Key Engineering Materials, 2019
Improvement of mechanical properties of light-weight corrugated core sandwich structures is a big demand in aerospace applications. Among these applications, space vehicles which encounter pressure loads and severe aerodynamic heating during ascent and reentry. The open-cell corrugated core is useful for active cooling of the sandwich structures.
