EXPERIMENTAL CONFIRMATION OF GUIDANCE PROPERTIES USING PLANAR ANISOTROPIC LEFT-HANDED METAMATERIAL SLABS BASED ON S-RING RESONATORS

We experimentally studied the guidance properties of the S-shaped metamaterial slabs. A peek of transmitted power due to the bulk guidance modes is observed in the negative band of the metamaterial, which is larger than a conventional dielectric waveguide made of FR4. The peek transmission frequency is shown related with the change of the negative band of the S-shaped metamaterial slab. Our results show good agreement with the theoretical predictions.
