The generation of terahertz frequency radiation (0.1-10 THz) is an important technological goal due to the use of this non-ionizing radiation to penetrate a wide range of non-conducting materials. One outstanding problem has been the propagation of THz radiation in guided wave devices. Few studies on the construction of efficient THz waveguide devices have been performed. We designed and simulated a metal-insulator-metal (MIM) slab THz waveguide device. We determined the propagation modes for the IR pump beam and generated THz beam using the RF mode solver, then we simulated THz generation for a laser pulse traveling through the waveguide using the time dependent RF solver.
