 Nov 30 awarded Popular Question Sep 29 revised Difficulty implementing equation describing angular response of fibre-optic hydrophone added work done Sep 29 comment Is there any way a longitudinal wave can have a shear velocity component? The fibre is a cylinder of diameter 125um - so for some wavelengths I suppose this could be considered a plate of sorts... Sep 29 comment Is there any way a longitudinal wave can have a shear velocity component? The medium of propagation is homogeneous (glass optical fibre) however it is surrounded by water so there is a change in acoustic impedance at the fibre boundaries.

Jul 2 awarded Organizer Jul 2 comment How can I validate a numerical model using an analytical solution of the same scenario? Hi Mike. Thanks for commenting :) I've added a bit more information above. Both solutions do have a constant, pure tone, however the numerical approximation cannot do this for a 'pure' sinusoid as it is temporally limited. Perhaps you are suggesting I run the simulation over a fixed period, 3 cycles say, and then use that in the comparison?
