3-Dimensional Anisotropic Split Resonant Cavity

An innovative 3-Dimensional split resonant cavity (SRC) is introduced here as an enhancement of planar split-ring resonators (SRRs), which could overcome the strong dependence of SRRs on polarization. Numerical simulations demonstrate that multiple resonances, including electric dipole mode, magnetic dipole mode and interaction of both modes, can be excited by three different polarized incident electromagnetic (EM) waves. Fano resonance characterized by asymmetric transmission line shape due to interference of multiple modes is observed in the simulation.
