In order to design and evaluate the behaviour of a numerically optimised wave energy converter (WEC), recommended procedure is initially study small scale models in controlled laboratory conditions then progress further up until full-scale reached. At any point, an important step correct selection theory model dynamical WEC. Most authors recommend based on dimensional parameters, which usually ...

Fiber Bragg gratings inscribed with a femtosecond laser using the point-by-point (PbP) technique have polarization dependent grating strength (PDGS) and exhibit birefringence. In this paper we quantify the dependence of these two properties on the ellipticity, position in the core and size of the micro-voids at the center of each refractive index modulation. We demonstrate that the effective mo...
