Electronic aspects of propagation in left-handed guided wave structures: electromagnetic-media interactions

Dispersion diagrams and magnetic and electric field distributions are found for a microstrip structure containing a left-handed medium (LHM). The material constituting the LHM making the substrate has characteristics chosen to overlap with potentially realizable substances. Calculations are done using a fast solver Green´s function spectral domain computer code. It is found that the dispersion diagrams and field distributions are very unusual and admit the possibility of completely new device realizations based on combining LHM with conventional materials in a multi-layered configuration.
