Small mode volume topological photonic states in one-dimensional lattices with dipole-quadrupole interactions
We study the topological photonic states in one-dimensional lattices analog to the Su-Schrieffer-Heeger model beyond the dipole approximation.The electromagnetic resonances of the lattices supported by near-field interactions between the plasmonic nanoparticles are studied teal horse blanket analytically with coupled dipole-quadrupole method.The to
