Abstract :
Anti-ship mines can be detonated by the electromagnetic signature of a surface ship [1]. Electromagnetic (EM) simulation is being developed to assess the propagation of these signals using the finite-difference time-domain (FDTD) method [2-5]. A previous paper has described this and demonstrated the accuracy [6]. A near-field to far-field transformation is being utilized to extend the reach of an FDTD simulation without using extraordinary computer resources.
