Abstract :
It is shown that realistically complex microstrip circuits can be rigorously analyzed on a small computer by means of the spectral domain technique in combination with precomputed basis functions and the use of the asymptotic forms of the Green´s function and the fast Fourier transform (FFT) algorithm. The results compare well with published measurements and with calculations using finite-difference time-domain (FDTD) method
