2. 1. A Fast Method for Solving the Helmholtz Equation Based on Wave Splitting

   Author : Jelena Popovic; Olof Runborg; Elisabeth Larsson; KTH; []
   Keywords : Helmholtz equation; high fequency waves;

   Abstract : In this thesis, we propose and analyze a fast method for computing the solution of the Helmholtz equation in a bounded domain with a variable wave speed function. The method is based on wave splitting. The Helmholtz equation is first split into one--way wave equations which are then solved iteratively for a given tolerance. READ MORE
