2 Zero-Index Metamaterials
plates serving as electrodes for the application of electric field. The refractive index
of the electro-optic material depends on the applied electric field. One can advance
a step ahead by making the rods too, of a different electro-optic material. Though
we have neither experimentally nor numerically analyzed the electro-optic design,
we believe that the idea is fascinating and worth investigating. The advantage of
dynamic methods is that there will be no need of making several structures, because
a single structure can be used for a broad range of wavelengths, merely by altering
the surrounding conditions. In all the tuning techniques discussed above, a universal
rule must always be satisfied, i.e., a well-defined Dirac cone must be obtained in the
band structure. If such techniques are successfully developed and mastered, it will
be very beneficial and cost-effective for integrated optics applications.
