Through integrative computational modeling, 3D printing, and vibration testing we demonstrate that the proposed lattice metamaterials can exhibit broad and multiple omnidirectional band gaps over a wide range of the geometry parameters that define the ligament.
We report the existence of multiple omnidirectional defect modes in the zero-¯n gap of photonic stacks, made of alternate layers of conventional dielectric and double-negative metamaterial, with a polaritonic defect layer.
These studies are important for applications using multiple SP resonances.
Thus, the MNS-NG nanostructure provides distinct higher-order modes and multiple Fano resonances.
These multiple Fano resonances could find applications in plasmon line shaping, multi-wavelength SERS, and biosensing.
The different spectral features associated with multiple Fano resonances each correspond to distinct plasmonic modes.
Multiple Fano resonances are observed with prominent modulation depth by breaking the symmetry of the structure.
The multiple Fano resonances in DNS nanostructure are obtained for the first time in this paper.
It predicts the multiple subharmonic resonances, period doublings, and some chaotic regimes found experimentally.
