Abstract
Conference Title: 2014 IEEE International Symposium on Antennas and Propagation & USNC/URSI National Radio Science Meeting Conference Start Date: 2014, July 6 Conference End Date: 2014, July 11 Conference Location: Memphis, TN, USA The conventional FDTD technique utilizes time domain numerical convergence as the criterion for termination; hence, its computational cost is high when accurate results are needed for high Q systems; for low frequencies; or when we have to deal with dispersive media. In this paper, signal processing techniques are employed to reduce the computational cost associated with the FDTD, especially for the situations mentioned above, and render the technique more efficient than the conventional FDTD.
