What is it about?
The relation between bandwidth and delay is highlighted. It is then used to design and realize a very high delay line by engineering its bandwidth. Bandwidth engineering is a typical application of meta-material. Therefore the line is studied through the prism of metamaterial.

Why is it important?
Usually purely electrical delay line are low pass systems such as coaxial or LC structure. It is demonstrated here that buy considering the line as a metamaterial, one can reach far better performances.
