Plasmonic Interference-Based Refractive Index Sensor Designed with Spectral Analysis and Structure Optimization

Surface plasmon polaritons enhanced magnetic plasmon resonance for high-quality sensing

“…[1][2][3][4][5][6][7][8][9][10][11][12][13] This is because micro-nano structures can control the flexibility of optical behavior to varying degrees, such as light-emitting devices, biosensors, and nanolasers. [14][15][16][17][18][19][20][21][22] When the free electrons in the metal are excited by electromagnetic waves, the phenomenon of electron collective coherent oscillation is surface plasmon resonance (SPR). SPR needs some special structures to be excited, such as a prism, grating waveguide mode coupling, [23][24][25][26] etc.…”
