An Efficient Laguerre-FDTD Algorithm for Exact Parameter Extraction of Lossy Transmission Lines摘要
This paper introduces a hybrid finitedifference time-domain (FDTD) method with weighted Laguerre polynomials to extract attenuation constants of lossy transmission lines. In the case of uniform lossy transmission lines, the complex variable compact two-dimensional (2-D) Laguerre-FDTD method is suitable for extracting attenuation constants exactly. To reduce memory requirements in this method, the divergence theorem is used to obtain a memory-efficient matrix equation. A lossy coplanar waveguide (CPW) example is presented to validate the accuracy and efficiency of the hybrid algorith
