Finite element simulation of core inspection in helicopter rotor blades using guided waves.
Chakrapani SK, Barnard D, Dayal V. Chakrapani SK, et al. Ultrasonics. 2015 Sep;62:126-35. doi: 10.1016/j.ultras.2015.05.009. Epub 2015 May 23. Ultrasonics. 2015. PMID: 26048172
Numerical simulations showed that a Lamb wave excited in the spar section of the blade gets converted into Rayleigh wave which travels across the spar-core section and mode converts back into Lamb wave. Dispersion of Rayleigh waves in multi-layered half-space was al …

A numerical model for ocean ultra-low frequency noise: wave-generated acoustic-gravity and Rayleigh modes.
Ardhuin F, Lavanant T, Obrebski M, Marié L, Royer JY, d'Eu JF, Howe BM, Lukas R, Aucan J. Ardhuin F, et al. J Acoust Soc Am. 2013 Oct;134(4):3242-59. doi: 10.1121/1.4818840. J Acoust Soc Am. 2013. PMID: 24116520
Here a single theoretical framework is used to predict the noise level associated with propagating pseudo-Rayleigh modes and evanescent acoustic-gravity modes. The latter are dominant only within 200 m from the sea surface, in shallow or deep water. At depths larger than 5 …

Some characteristics of an extremely-short-external-cavity laser diode realized by butt coupling a Fabry-Perot laser diode to a single-mode optical fiber.
Sidorin Y, Howe D. Sidorin Y, et al. Appl Opt. 1998 May 20;37(15):3256-63. doi: 10.1364/ao.37.003256. Appl Opt. 1998. PMID: 18273278
When butt coupling a Fabry-Perot laser diode to an extremely closely spaced waveguide (separation less than or equal to a few times the Rayleigh range of the laser beam), there is a trade-off between the optimal power coupling and the variation of the coupled laser diode's …
