Abstract :
Green´s function asymptotic properties of the wave field in a periodic medium is analytically examined. The solution is constructed by the stationary phase method. It is shown that some singularities occur in this approach. Therefore, we focus on the description of the vicinity of a singular cone where the usual stationary phase method fails and determine a smooth transition from the standard asymptotic form to the new one. A detailed analysis of the obtained results is given.
