    Abstract

    A hybrid Method of Moments/Finite Difference Time Domain (MoM/FDTD) approach is used to characterize UHF/VHF propagation over irregular terrain. The effect of terrain on path loss is examined. Of particular interest is the shadow region behind the hills. The standard NEC-4 MoM code is used to determine the fields propagated by the antenna over flat earth. A two dimensional FDTD code is used to calculate the fields in the area of the terrain feature. The vertical field calculated by FDTD is converted to path loss for display.
