Abstract
In one exemplary embodiment, a transmission line geometry or structure may readily be realized as periodic printed coupled/uncoupled microstrip lines on dielectric and/or suitable biased ferromagnetic substrates. An example of a transmission line geometry or structure may be adapted to emulate extraordinary propagation modes within bulk periodic assemblies of anisotropic dielectric and magnetic materials. For instance, wave propagation in anisotropic media may be emulated by using a pair of coupled transmission lines () having a specially designed geometry, thereby enabling mold wave dispersion in a microwave or optical guided wave structure. Degenerate band edge resonances, frozen modes, other extraordinary modes, and other unique electromagnetic properties such as negative refraction index may be realized using unique geometrical arrangements that may, for example, be easily manufactured using contemporary RF or photonics/solid state technology.
