Abstract : Millimeter and sub-millimeter wave three-dimensional open dielectric structures are characterized using the Finite Difference Time Domain (FDTD) technique. The use of FDTD method allows for the accurate characterization of these components over a very wide frequency range. Three different sub-mm wave transitions to layered ridge dielectric waveguide (LRDW) are analyzed. These are found to be efficient over a wide sub-mm frequency band which makes them useful for a variety of applications. Theoretical results for a mm-wave image guide coupler show good agreement with experimental data. Sub-mm wave LRDW directional couplers are analyzed. A 3-db, 500 GHz coupler with negligible radiation loss is designed using an interative procedure. This shows that the FDTD technique can be used not only as an analysis method, but also as a design tool which takes into account all high frequency parasitic effects. A matched termination for the LRDW is described and analyzed.
