In addition, for nonzero stationary forcing, we show that there is a local absorbing ball and that the corresponding nonlinear semigroup is compact for all t >amp;gt; 0.
      
Ellipsoidally-shaped local absorbing boundaries for three-dimensional scalar wave propagation
      
For the first time, a finite difference method equipped with the exact local 'absorbing' conditions on artificial boundaries has been applied for the solution of this kind of open problems.
      
It is realized that, for a given mesh, the method presented is computationally slower than a method based on a local absorbing boundary condition but in on the other hand the method is much faster than the readily used method of moments.
      
Local absorbing boundary conditions couple only nearby spatial locations and time stations.

The finite difference time domain (FDTD) computational zone was truncated by an artificial boundary, of which the geometric shape was conformal with the boundary of an arbitrary shaped scatterer. The external conformal mesh was generated by the Thompson transformation.On the truncating boundary, the time domain measured equations of invariance (MEI) were applied as a local absorbing boundary condition. So the FDTD computational domain was compressed remarkably. The numerical experiment proved that the requirement of computer storage is reduced while the numerical accuracy is not decreased.

In the paper, we approximate the two dimensional wave equation to obtain a new absorbing boundary condition. We call it local absorbing boundary condition (LABC). It is more effective both in theoretical analyses and numerical simulations when compared to other widely used boundary conditions such as second order Mur ABC's. At the same time, there is a little increasing for the CPU time and requirements of computer memory. We simulated a sample of a plane wave propagating in a multi layer media with...

In the paper, we approximate the two dimensional wave equation to obtain a new absorbing boundary condition. We call it local absorbing boundary condition (LABC). It is more effective both in theoretical analyses and numerical simulations when compared to other widely used boundary conditions such as second order Mur ABC's. At the same time, there is a little increasing for the CPU time and requirements of computer memory. We simulated a sample of a plane wave propagating in a multi layer media with this new absorbing boundary condition. The numerical results show it is more effective than the second order Mur ABC's.
