Abstract :
A compact 2-D full-wave finite difference frequency domain method (2-D CFDFD) with the surface impedance boundary condition (SIBC) is employed to analyze the dispersion characteristics of lossy microstrip structure. Only four transverse field components are involved, the SIBC can also be easily implemented. Propagation constant can be obtained as solution of eigen value problem at a given frequency, and the effects of the key parameters on attenuation constant are presented.
