Modulation of Surface Plasmonic Bending Beam via Nanoslit Interactions
The discussion of resonance mechanisms for artificial structural units has always been a key to producing highly efficient, active and tunable meta-devices in the fields of controlling surface plasmon polaritons (SPPs) to generate surface plasmonic bending beams (SPBs).In this study, an array Wood Sculpture of 20 antisymmetric double V-shaped struc
