Hi.
I encountered the attached dispersion diagram when reading a paper "Periodic Analysis of a 2-D negative refractive index transmission line structure" IEEE Transactions on Antena and Prop. Vol. 51 No. 10 Oct. 2003. It is said to be a brillouin diagram. Could anyone explain to me what the parameters such as G, M X stands for and how can we plot such kind of diagram.
Any good tutorials on this topics?
Thanks in advance.
