Abstract :
A new techniue based on the spectral domain method for calculating the characteristic impedance of planar dispersive structures with multilayer dielectric substrates is presented. The coupling and decoupling of LSE and LSM modes are introduced so that the calculation of whole power in the considered structure bcomes very easy and fast. Numerical results are presented for some complex structures.
