✦ Synopsis

Collected f 0 results are shown in Figure 15. The center frequency varies with s/(s ϩ w g ) ratio around the theoretical value c 0 /(4h g ) ϭ 1 GHz. However, it is noted that as the period length decreases (that is, (s ϩ w g )/ G decreases), f 0 depends less on the s/(s ϩ w g ) ratio. The dependence of f 0 on the incoming angle is small: f 0 tends to rise a little bit, when the incoming angle is changed from 90°to 45°.

5. CONCLUSION

Plane-wave scattering from finite-width corrugated plates has been studied using a 2D model and the MoM. Also, the reliability of the modelling method has been investigated. How the reflected-field polarization depends on the frequency and on the incoming angle has been of special interest. The frequency dependency of polarization has been studied via helicity p( f ). The results have shown how various parameters-the total plate width W p , bottom-plate thickness t B , groove-wall thickness s, period length, and incoming angle-affect the reflected-field helicity and bandwidth of a corrugated plate.
