These experiments requires modification of the usual quantum mechanics. Illustrated by the treatment of the beam splitter presented here. Be lossless.The electromagnetic fields associated with a beam splitter having two input arms and two output arms are quantized in terms of the spatial modes of the. Recent years2 has rekindled interest in the lossless beam splitter, not. The quantum-mechanica...

In this paper, a comparison of weak-form Galerkin and least-squares finite element models of Timoshenko beam theory with the von Kármán strains is presented. Computational characteristics of the two models and the influence of the polynomial orders used on the relative accuracies of the two models are discussed. The degree of approximation functions used varied from linear to the 5th order. In ...
