“…Figure 4 shows the results obtained for normal incidence and TE polarization using a finite structure of 10x10 elements using different meshes: different number of observation points and heights. Results are compared with [3] and good results can be observed. Notice that when the observation points are not enough, the reflection coefficient is greater than 1.…”

“…The incidence of the plane wave is normal to the structure and TE polarization. The second case analyzed is a two layered strip gratings structure [3] separated 2 cm and the relation between length and wide is 0.25, being the size cell 1 cm by 1 cm. Figure 4 shows the results obtained for normal incidence and TE polarization using a finite structure of 10x10 elements using different meshes: different number of observation points and heights.…”

This paper presents an application of the MLFMA to the analysis of conformed and finite-sized multilayered periodic structures modeled by parametric surfaces. Using these surfaces, the discretization, basis and test functions are conformed to any curved surface, with the advantage of an exact representation of the geometry. Using MONURBS [1], a moment method code, the scattering field of several samples points over the surface are obtained, so the reflection and transmission coefficients can be calculated. This method has been tested in several periodic structures achieving good results.

“…The multilayer first period should be specified and the system found by studying the structure in its entirety. In general, given any multilayer structure, it is possible to find a period in the global system, although in some cases this period may be much higher than that of the individual subsystems [6], [7].…”

This paper describes the entire analysis of a double screen FSS. Two single layers compose the structure. Each single layer is composed of conducting patches on isotropic dielectric materials. The relation between scattered fields and the current sources is presented. The analytic procedure to get the dyadic Greens function and the incident fields is detailed. The numerical procedure to get the induced density current on patches and, so, the scattered fields is also presented. Finally, we show how to transfer the impedance seen by the current sources for the top and the base of the structure.

“…The cascading approach, mentioned above, provides a way to overcome these difficulties by employing the GSM technique [5,6]. In this method, the reflection and transmission properties of FSS screens are first described in terms of scattering matrices, and a linear system approach is subsequently applied to the cascaded screens to derive the scattering parameters for the composite.…”

“…In this method, the reflection and transmission properties of FSS screens are first described in terms of scattering matrices, and a linear system approach is subsequently applied to the cascaded screens to derive the scattering parameters for the composite. This approach has been successfully applied to the problem of analyzing FSS screens with identical periods in [5], and has later been extended to the case of screens with periods whose ratio is a rational fraction [6]. However, the scattering matrix approach, which is computationally far more efficient than the one-step approach, is not without its drawbacks.…”

An efficient technique for analyzing multiple frequency‐selective‐surface screens with dissimilar periods

A mixed coupling structure has been proposed for the cross coupling of a comb-line filter. The mixed coupling is a result of the superposition of the electric coupling by an electric probe and the magnetic coupling by a coupling window between nonadjacent comb-line resonators. It is shown that the desired electric coupling can be achieved easily with a tuning screw in the magnetic coupling window region. Moreover, the fabrication errors and the errors due to the adjacent coupling structures can be compensated for easily, and tuning the positions of the transmission zeros is easy with the proposed structure.The validity of the mixed coupling structure was verified by applying it to the cross coupling of a four-pole comb-line bandpass filter. The theoretical and measured responses of the examined filter show good agreement with each other.
