| Outline of Final Research Achievements |
A uniaxial anisotropic optical medium called a hyperbolic metamaterial (HMM) has a hyperbolic dispersion relation and exhibits special propagation characteristics different from a dielectric. We conducted research on propagation modes of HMM and obtained the following results. 1) Bulk propagating waves in HMMs have been treated by the effective medium approximation, but we found a mode that cannot be explained by the approximation and classified them by the symmetry of the surface plasmon coupling mode. Moreover, the limit of approximation was clarified. 2) It was theoretically proposed that the resonant wavelength of the HMM optical resonator does not depend on the size. This is a revolution in the concept of optical resonators. This makes it possible to realize a new metamaterial using HMM optical resonators as metaatoms.
