Low loss left-handed media using dielectric ring resonators
Paper i proceeding, 2008

A low loss left handed 1D media using thick film technology is proposed in this work. The design uses a rectangular cut off waveguide periodically loaded by high permittivity dielectric ring resonators. These are considered as a low loss replacement for the split-ring resonators (SRR), responsible for magnetic activity of the media. Simulations are made using eigen-mode solver of HFSS. There the periodic boundary conditions are utilized to emulate the effect of the infinite media. The analysis reveals the propagation of the backward waves below the cut off frequency of the WG indicating left handedness of the propagation media. Another pass-band with the forward wave exists below the cut off of the WG. It is shown that two first pass-bands can be linked so that continuous backward-to-forward transmission is observed.
