Metamaterial structures are artificial materials that show
unconventional electromagnetic properties such as photonic band-gap,
extraordinary optical transmission and left-handed propagation. Up to now,
relations of photonic crystals and negative refraction have been shown as
well as of photonic crystals and sub-wavelength hole arrays. Here we report
a left-handed metamaterial engineered by a combination of sub-wavelength
hole array plates periodically stacked to form a photonic crystal structure. It
is shown the possibility of fine-tuning the metamaterial in order to permit
extraordinary optical transmission and left-handed behaviour. Our work
demonstrates the feasibility of engineering left-handed metamaterials by just
drilling holes in metallic plates and brings together single structure photonic
crystals, extraordinary optical transmission and left-handed behaviour.
