Abstract
The approach of the metamaterials based on the theory of transmission lines has an influence on the development of the radiofrequency domain, so the types and techniques of elaboration of these artificial lines are quite diversified. This paper will present two models of Artificial Transmission Line CRLH (Composite Right Left Handed) composed of a combination of resonators OSRR (Open Split Ring Resonators) and OSCRR (Complementary Open Split Ring Resonators). This paper will also show how the Scattering Bond Graph (SBG) study methodology allows to provide electromagnetic simulation results (Scattering parameters, phase response) more conducive to Bond Graph (BG) modeling, and will prove the possibility of having the most perfect line (solved the problem of impedance adaptation) and better understanding of the behavior of radiofrequency systems.
Highlights
The development of the communication system imposes the evolution of the modeling and study techniques of hyperfrequency systems
The second proposal for a COMPOSITE RIGHT/LEFT HANDED (CRLH) transmission line is represented by Fig. 11 where it consists of two OSRR resonators and an OCSRR resonator that are cascading
We modeled the equivalent circuits of the resonators OCSRR and OSRR, and we developed the wave matrix [W] by applying the properties of the bond graph
Summary
The development of the communication system imposes the evolution of the modeling and study techniques of hyperfrequency systems. Despite the many advantages of the metamatrials techniques [2], the analysis of microwave circuits remains difficult and has problems especially adaptation and modeling that requires manufacturers to redo the complete study to change some parameters which plays a role negative role on the effectiveness of the results obtained. The second part is reserved for the development of two new CRLH transmission line structures, and to study the physical characteristics of each structure from the [W] wave matrix. Where this matrix describes the relations between the incident waves and reflects whatever the complexity of the system. The reliability of the methodology is determined from the level of adaptation of the transmission lines and the total transfer of the incident waves
