A GTEM Chamber Design with Frequency Flexibility Using Metamaterial Concepts on the Septum

Abstract

In this work it is shown the strategy of use metamaterial technology to improve the GTEM chamber performance. The analysis and characterization of different types of metamaterial patterns, such as fractal cells, Jerusalem-Cross-Pair, SRR-Split Ring Resonator and CSRR-Complementary Split Ring Resonator printed on the septum of a GTEM chamber was done. The main goal is to give a flexibility frequency range for electromagnetic compatibility analysis of integrated circuits and electronic boards. Experimental results are compared to simulated ones showing the advantages of the tuned characteristic of the patterned septum in comparison to the conventional type. This technique appears as an option for the performance optimizations of compact GTEM chambers.
