Abstract
Following consumer demand, international competition has become increasingly high, suddenly industrialists are mobilizing to meet the requirements. Faced with this challenge, and in order to be able to respond to these prerequisites, manufacturers are looking for techniques that will allow them to gain productivity by increasing the rate of perfection before going to manufacturing. Modeling presents the most important phase in a construction chain since it allows not only analysis and understanding of the physical system but also to improve its behavior according to the desired objective from the design phase. The results presented in this article concern the modeling of the transmission lines of metamaterials loaded with OSRR Split-Ring Resonators and COSRR Complementary Open Split-Ring Resonators resonators, with the aim of improving analysis, synthesis and understanding of this system. By using the Scattering Bond Graph technique, which improves the adaptation of the impedance, and reduces the bandwidth. This technique allows us to deduce the scattering parameters (matrix [S]) of the OSRR / COSRR TL elements from the wave matrix [W], hence this matrix is determined through on the specific properties of the equivalent Bond Graph presentation based on the notion of causality.

A new expression appeared in the universe of the microwave, it is the metamatriaux [1]
In order to provide a general method and easier to handle for OSRR and OCSRR coupled to planar transmission lines
The objective of this work is to prove the contribution and the modelling of the new study methodology called dispersion link graph, in the analysis of transmission lines of metamaterials loaded with OSRR resonators "Open Split-Ring Resonators" and COSRR "Complementary Open Split-Ring Resonators" of equivalent electrical diagrams
Summary
A new expression appeared in the universe of the microwave, it is the metamatriaux [1] (artificial metallodiélecctric structuring properties not found in nature). Several metamatrial-based transmission line structures have been studied, these lines are implemented in charge of a transmission line with resonators such as OSRR and OCSRR [5], [6] These structures have already contributed to the growth of development of the design of new microwave circuit systems, but they still have drawbacks. The traditional techniques of studying in [1], [7] this type of structure can be long, complicated and require a thorough knowledge of the electromagnetic field, adding that they are expensive, without forgetting that it poses a huge problem of impedance adaptation For these reasons, we propose a technique of study allowing to evolve less complicated in terms of extraction of diffusion parameters (distribution parameters), and which proved the effectiveness of the physical models of system with microwaves, as well as than its precision in terms of adaptation. In order to provide a general method and easier to handle for OSRR and OCSRR coupled to planar transmission lines
