We can easily predict the free space loss from the well known equation: Free Space Loss = 32.45 + 20log(d) + 20log(f) dB(where d is in km and f is in MHz) - it is important to understand where this comes from. Imagine a light bulb in free space, light spreads out more or l...

space-time Wigner distribution functionultrashort pulsed beamsfree-space propagationOn the basis of the paraxial wave equation of ultrashort pulsed beams, the free-space propagation equation of the space-time Wigner distribution function has been derived. The propagation laws for the moments of ultra...
A method of evaluating free-space optical propagation characteristics includes emitting a plurality of laser beams from a corresponding plurality of laser sources, receiving laser beams at different target points, and measuring the time-based spatial fluctuations between the laser beams thus received. The...

The isoparametric formulation allows to move easily all the computations in the parent space. To this aim, the Jacobian matrix J is required to perform the coordinate change. In order to define this matrix, the derivates of the interpolating functions with respect to the natural coordinates ξ ...
The FBG sensors were mounted away from the edges of the plate, in order to have a maximum delay on the successive reflections of propagation wave, with no interference in the fundamental first part of the signal. The sensitivity and directionality tests were performed by a hammer test. All ...
