Abstract

Conventional moment method with subsectional bases and Dirac testing functions  reduces the analysis of symmetric planar microwave circuits to solving a system of linear  equation with block circulant coefficient matrix. A method is presented for diagcnalizing  this matrix using discrete Fourier transforms (DFT). It is shown that much economy in  memory space and computation time can be achieved by making use of the properties of  block circulants and by implementing the DFT's using last Fourier transform (FFT) techniques.
