Abstract :
A hybrid evaluation method using both the spectral- and the spatial-domain techniques is proposed for the evaluation of the Sommerfeld-type integrals resulting from the full-wave analysis of microstrip structures. This method combines the advantages of the spectral-domain for the evaluation of near fields and the spatial-domain method for the evaluation of far-fields. This method is simple and needs no additional formulations. It also provides an easy alternative method to handle the inefficiency of calculation with the singularity of the Green´s function. Numerical results are used to demonstrate the simplicity and the accuracy of this method.
