| 摘 要： | INTRODUCTION Left-handed materials (LHMs) are characterized by simultaneously negative permittivity and perme- ability. It was first investigated theoretically by Ve- selago (1968). The experimental realization of LHM with resonance structures was demonstrated by Smith et al.(2000). Since then, LHM has gained significant interest and started to be integrated into novel mi- crowave and optical applications. The transmis- sion-line (TL) approach was recently proposed to realize LHMs …

| Abstract: | A new approach was introduced to analyze composite right/left-handed transmission lines (CRLH TLs). The Bloch impedance and the dispersion relations are directly obtained from the S parameters of the unit cells. The LH and RH frequency bands are then identified by the real parts of the Bloch impedance and the phase delay of the unit cells. The new approach has some advantages over the LC parameters extraction method introduced by Caloz et al.(2004). Based on the new approach, a novel resonator is designed using CRLH TLs. The simulation and experimental results accorded well with the theoretical analysis. The novel resonator may have potential applications in filters with high harmonic suppression and compact structures. |
