A circuit model approach is here presented to characterize bi-dimensional arrangements of dual-polarized elements. This contribution is an extension of the physical insightful approach previously proposed by some of the authors. The main novelty here resides in the fact that the scatterer may support two different current profiles. This feature becomes crucial for the accurate characterization of...
A physical insightful and quasi-analytical circuit model is here proposed in order to characterize frequency selective surfaces composed by scatterers/apertures of arbitrary geometry. The present work is an extension of the approach previously proposed by some of the authors that dealt only with simple dipole-based periodic surfaces. In order to account for scatterers of more complex shape, their...
The disposal of an equivalent network representation to characterize the frequency behavior of grounded periodic arrays of printed patches is here combined with the assistance of full-wave electromagnetic simulator to achieve a very efficient method for analysis/design. The basic restriction of the present procedure is that the frequency band cannot be extended much beyond the first fundamental resonant...
A circuit model is here proposed to characterize grounded arrays of printed patches. This equivalent circuit reproduces the behavior of the structure in a wide frequency range with the only restriction of dealing with single resonant scatterers. Full-wave data is required to build some elements of the equivalent circuit. However, only a reduced number of simulations is needed, in contrast to other...
A technique for extracting the electrical and topological parameters of open defects in process monitor lines is presented. The procedure is based on frequency-domain measurements performed at both end points of the line. The location as well as the resistive value of the open defect are derived from attenuation and phase shift measurements. The characteristic defect-free impedance of the line and...
