Diffraction of a Gaussian light beam at the right-angle edges of a plate and the interference pattern in the shadow region

Application in light steel composites in floors

“…The difference is due to slip in the screw or nail attachments [10]. The results clearly show that the performance of the single web joists T1 was more affected by shear in the plywood and its fixings.…”

Beam diffraction by a resistive half-plane

“…However, they did not provide any numerical analysis of the fields. Recent studies on laser beam diffraction include 3D analysis, performed by the superposition of the diffracted waves by plane waves [12], and an experimental analysis of the scattering of a Gaussian beam by the edges of a plate [13]. Intensive study on the beam scattering by perfectly conducting half-planes and wedges was performed by Suedan and Jull [14][15][16][17].…”
