Study of the electric field enhancement of high impedance surfaces
High impedance electromagnetic surfaces (HIS) are known for many applications including low profile antenna design. However, in high power antenna designs using HIS, the air breakdown between neighboring elements is a limiting factor. We show that the electric field in the gap between neighboring elements is independent of the resonance quality factor of the HIS. Instead, the average electric field inside the HIS cavities (and therefore the stored energy) scales with the resonance quality factor (Q)
