3. Transmission lines and metasurfaces
So far, we've seen three-dimensional MMGs in microwave and optical applications. There are also one- and two-dimensional versions of these materials, each with its own specific properties.
Retrograde transmission lines were first proposed by L. Brillouin in a book published in 1946 . These are periodic lines made up of L-C cells, as shown in figure 24. A negative phase velocity c can be observed in these lines, and...
