Title Αριθμητικά πειράματα με τη μέθοδο των σωματιδίων για την εξίσωση Wigner σε υψηλής συχνότητας παραβολική διάδοση
Alternative Title Numerical experiments with the particle method for the Winger equation in High-frequency paraxial propagation
Creator Fregadakis, Emmanouel J
Abstract In this work we perform some numerical experiments for the Wigner equation, at relatively high frequencies and for models whose fields develop caustics, by using the particle method and the particle-in-cell technique. The accuracy and the efficiency of the particle method is investigated using either analytical solutions of the Wigner equation or FEM solutions of the associated wave field.
