Abstract :
The dependence on substrate thickness of the resonance frequencies of dipole, square loop and circular patch FSSs is examined. Circular patches contain less fine scale structure, requiring fewer high order Floquet field modes. The evanescent fields are less tightly bound and the air/dielectric boundary is significant at greater substrate thicknesses.
