Abstract :
A class of two-dimensional and three-dimensional monolithic microwave integrated circuit (MMIC) structures is analyzed theoretically using an efficient iterative technique. The transfer-matrix approach to constructing the spectral Green´s functions of multilayered structures is adopted. Discretization of the continuous functions and utilization of the periodicity of the MMIC structures enclosed by sidewalls lead to a discrete convolution operation, which is carried out efficiently using the FET (fast Fourier transform) algorithm. The spectral Green´s functions are modified for both the periodic and aperiodic structures to improve the numerical efficiency of the iterative algorithm. Numerical results are presented and compared with available data
