FDTD and Monte Carlo methods are combined to simulate the terahertz radiationfrom a coplanar photoconducting structure. The simulation tool under considerationallows calculation of potentials, particle distributions, current densities, and the nearfield electromagnetic fields anywhere in the computational domain. To model the farfield radiation, it is not efficient nor, in many cases, physically possible at present to usethe FDTD technique directly because of the excessive computational burden.Techniques are discussed for modeling both the near field and the far field radiation.Computational results showing the far field radiation are in qualitative agreement withpublished experimental results
