Abstract
Electromagnetic scattering characteristics of dielectric gratings are examined numerically using the finite-element method. The gratings are created by introducing pressurized dielectric fluid into periodic tubes within a dielectric sheet. A structure is presented which has an extremely narrow stop-band (total power reflection) immediately adjacent to a passband (total transmission). It is shown that the critical bands can be shifted by changing the fluid pressure, at a cost of only slightly less than perfect passband transmission (97%), while the rejection band remains perfect (100%). Thus, a unique tuneable, switchable frequency selective surface can be easily realized.<>Keywords
