Modelling metamaterial transmission lines: a review and recent developments

Abstract

This review paper is devoted to the discussion and comparison of the lumped element equivalent circuit models of the different types of metamaterial transmission lines that have been proposed so far, namely the CL-loaded lines, and those lines based on the resonant type approach. The latter category comprises both artificial lines loaded with split ring resonators (SRRs), or related topologies, and metamaterial transmission lines based on complementary split ring resonators (CSRRs). It will be the main aim of this paper to clearly justify the circuit elements of the models (and link such elements to the line physics and topology), to compare the different lines to the light of these models, and to point out the advantages and drawbacks of the different metamaterial transmission lines. As long as metamaterial transmission lines are exhaustively used for the design of compact microwave and millimeter wave components with improved performance and/or based on new functionalities, and their synthesis is based on the lumped element equivalent circuits, this paper is of actual interest for RF/microwave engineers and in general to those readers involved in metamaterial research and applications.

Recent Advances in the Modeling of Transmission Lines Loaded with Split Ring Resonators

“…By using these reactive parameters, the circuit response can be inferred. The results, also depicted in Figure 2(b) [33], validate the circuit model of Figure 1 (note that the agreement between the circuit and electromagnetic simulation is very good).…”

“…The extracted circuit parameters are = 1.91 nH, = 2.07 pF, = 0.24 nH, and = 23.01 pF. From[33], reprinted with permission.…”

The chiral nano-world: chiroptically active quantum nanostructures

“…Another novel CPL emissive structure utilises a U shaped split ring resonator (SRRs), which have been the subject of extensive research in the last 10 years. [85][86][87][88] The SRRs act as a multipolar nanoantenna coupled to a semiconductor QD, showing emission at around 800 nm. 89 This specific SRR is arranged in a periodic lattice, with a lattice constant of 300 nm on a glass substrate and was covered with an MgF 2 spacer.…”

Design a CRLH Antenna for MIMO Applications with Single and Dual Band

“…In 2002, the conception of composite right/left-handed (CRLH) transmission line (TL) metamaterials (MTMs) or planar negative-refractive index TL had been generalized to offer the implementations the practical applications for engineering in MTMs [1]. Such a paradigm has been exhibiting a rich potential possessing in electromagnetics engineering of the microwave devices with unusual properties [2].…”
