Two printed photonic band-gap surfaces presenting electromagnetic band-gaps are introduced and analyzed. The geometries of the surfaces and consequently the number and characteristics of the band-gaps can be modified via electronic control components. The reported properties of the surfaces rely on their dispersion diagrams and have been studied by full-wave electromagnetic simulation.
A parametric study of a high impedance surface built in microstrip technology is reported and the feasibility of an electronically switched parallel-plate waveguide is demonstrated. Full wave electromagnetic simulation is used for obtaining relevant parameters and for operation demonstration.
