EFFECTS OF HIGH-ORDER MODE-COUPLING IN DIELECTRIC COVERED FINITE ARRAY OF DISSIMILAR RECTANGULAR WAVE-GUIDES

Expressions are presented for the computation of mutual admittance bet ween rectangular apertures of different size, in a finite planar array , The equations allow any orientation for any of the apertures, with a ny number of transverse electric (TF) and transverse magnetic (TM) wav eguide modes, Furthermore, the expressions also include the effect of dielectric covering of these apertures, A versatile software package, useful for the design and analysis of finite phased arrays, is produce d incorporating these features, and its extensive validation is provid ed.
