Numerical Simulation of Acoustic Waveguides for Webster-Lokshin Model Using Diffusive Representationlent diffusive realizations may be proposed, that are deeply linked to choices of cuts in the complex analysis of the transfer functions. Then, finite order approximations are given for their simulation (§4).

High-Order Numerical Simulation of Rocket Launch Noise Near the boundaries the method is third order accurate and satisfies the Summation by Parts property. This guarantees strict stability for linear problems. The classical explicit fourth order Runge-Kutta method has been used for time integration.

Computing Solutions for Helmholtz Equation: Domain Versus Boundary Decompositiondifferent kind of discretization or algorithms (integral equations or asymptotic formulas…) one is led to use . techniques. This technique can be also useful when the scatterer is too huge, or when distributed computation is the aim. We give here a domain decomposition algorithm to compute acoustics

A Eulerian Geometric Optics Method for High Frequency Electromagnetic Fields Computations in Presencon-Jacobi type equation in a particular geometric setting. More precisely we consider the fold caustic case. 2) The computation of the amplitudes needed to evaluate the electromagnetic field. 3) A numerical investigation of the asymptotic validity of the obtained “High frequency” GO solution and its

Exact and High-Order Non-Reflecting Computational Boundariesous fields of application involving wave propagation, such as acoustics, electromagnetics, meteorology and solid geophysics. The main four types of methods that have emerged are: boundary integral methods, infinite element methods, absorbing layer methods and Non-Reflecting (or Absorbing) Boundary C
