Controlling the wavefront of an extreme ultraviolet (XUV) high-order harmonic beam during generation process offers capability modifying properties without resorting to any XUV optics. By characterizing intensity profile and wavefront, we quantitatively retrieve both size position waist each generated in argon jet. We show that optics-free focusing can occur under specific generating conditions...

in this paper, a closed form solution for bending and free vibration analyses of simply supported rectangular laminated composite plates is presented. the static and free vibration behavior of symmetric and antisymmetric laminates is investigated using a refined first-order shear deformation theory. the winkler–pasternak two-parameter model is employed to express the interaction between the lam...
