“…Using both E and H information, the solution is more robust than using either alone. The FDTD method has been applied to the analysis of microstrip line structures and there are many excellent papers on the use of FDTD in TL structures (see [7,8]). Therefore the details of the FDTD method are henceforth bypassed.…”

Abstract-In the present paper the response of V transmission line to electromagnetic illumination has been obtained. Also in order to determine the VTL frequency operation band for both TE and TM modes a Gaussian pulse source has been applied to the structure. The VTL structure has received considerable attention in high frequency and microwave IC packaging. The purpose of this study is to determine high frequency design considerations in order to reduce the effects of electromagnetic interference (EMI) on the VTL structure and maintain the desired performance. It was observed that the effect of incident EM waves on the V lines performance is considerably lower than conventional microstrips, however the V lines are more sensitive to sources at close proximity. In addition, although the V lines show lower dispersion at higher frequencies, their frequency operation band is limited by a resonance like behavior which is directly related to the V groove dimensions. The full wave analysis is carried out using the Yee-cell based 2 Dimensional Finite Difference Time Domain method (2D-FDTD), while enforcing a very stable and efficient mesh truncation technique.

“…A compact two-dimensional (2-D) scheme is applied to fullwave analysis of uniform and infinitely long transmission lines to reduce memory requirement and shorten computation time [12,13]. However, in case of fine grid division, the Courant-Friedrich-Lewy (CFL) stability condition imposes tiny time steps and results in a long solution time.…”

“…Two important problems, which have received a broad attention in literature, arise in the simulation of multimode waveguides by time domain methods: on one hand, the correct excitation of the incident modes at the feeding port and, on the other hand, their subtraction at the end of the guide [17][18][19][20][21][22][23][24][25][26][27].…”

Abstract-In this paper, we present a procedure to calculate the discrete modes propagated with Crank-Nicolson FDTD in metallic waveguides. This procedure enables the correct excitation of this kind of waveguides at any resolution. The problem is reduced to solving an eigenvalue equation, which is performed, both in a closed form, for the usual rectangular waveguide, and numerically in the most general case, validated here with a ridged rectangular waveguide.
