The application of the FDTD method to millimeter-wave filter circuits including the design and analysis of a compact coplanar strip filter for THz frequencies

The finite difference time domain (FDTD) method is applied to the analysis of microwave, millimeter-wave and submillimeter-wave filter circuits. In each case, the validity of this method is confirmed by comparison with measured data. In addition, the FDTD calculations are used to design a new ultra-thin coplanar-strip filter for feeding a THz planar-antenna mixer. In this instance, the FDTD analysis is confirmed by microwave scale model measurements and by simulations performed with Hewlett Packard's Microwave Design System (MDS).< >
