WAVE-PROPAGATION IN A PERIODIC MICROSTRIP LINE ON A MULTILAYERED ANISOTROPIC SUBSTRATE

An efficient spectral domain full-wave algorithm based on 4 x 4 transf er matrix and integral equation method is developed for the periodic m icrostrip line on the multilayered anisotropic substrate, The substrat e may consists of arbitrary number of layers whose permittivity and pe rmeability are tensors of general form, It is shown, that in some case s, the quasistatic approach for calculations of characteristics of the dominant mode may be invalid even at very small frequencies. The meth od may be used for simulation of integrated circuits, which include an isotropic layers.
