An improved complex permeability model for litz wire windings is derived heuristically from a comparison between simulation results and the standard analytical model. It is valid for all strand diameters, strand distances and frequencies, and may be used for accurate numerical calculations of magnetic fields and losses in magnetic components.
We describe the development, construction and sea testing of an underwater holographic camera (HoloCam) for in situ recording of marine organisms and particles in large volumes of sea water. HoloCam comprises a laser, power supply, holographic recording optics and plate holders, a water-tight housing and a support frame. Added to this are control(More)
