New approach to far field analysis for radiation pattern estimation using FDTD method

New approach to far field analysis for radiation pattern estimation using FDTD method

In this paper an approach to efficient computation of radiation pattern in FDTD simulation environment is presented. A necessary large distance from the radiating object is achieved by multigrid space discretization with unilaterally connected subdomains. A numerical dispersion is reduced u...
