Application of signal-processing techniques to reduce the errors related to the FDTD excitations
A study on the reduction of the errors related to the finite-difference time-domain (FDTD) excitations was performed by employing signal-processing techniques. Plane-wave scattering problems were simulated. The improvements ...
Accurate plane-wave excitation in the FDTD method
Different techniques are developed to implement plane-wave excitation on the finite-difference time-domain (FDTD) method, such as the initial-condition, the hard-source, and the connecting-condition techniques, for the ...
Subsurface-scattering calculations via the 3D FDTD method employing PML ABC for layered media
A three-dimensional finite-difference time-domain method that employs pure scattered-field formulation and perfectly matched layers (PML) as the absorbing boundary condition is developed for solving subsurface-scattering. ...
