Název v původním jazyce

Design, simulation and optimization of silver nano-grating for optimal SERS response

Popis výsledku v původním jazyce

In the paper are presented results of the design, simulation and optimization of a planar structure to surface enhance Raman spectroscopy (SERS) based on surface plasmon-polariton (SPP) effect used in a surface silver layer deposited on a SU-8 nano-grating. The behavior of the Ag-SU8 nano-grating and consequent SPP phenomenon was studied and simulated by solution of Maxwell's equations in periodic dielectric structures - Rigorous Coupled Wave Analysis (RCWA) algorithm enhanced by Modal Transmission Line. The convergence and simulation studies were performed for optimization of SPP structure parameters. It was found by simulation that the narrow range of grating periodicity and metal layer thickness exist, where SPPs effect can be most efficiently excited. Results and optimization of designed structure were used for fabrication of reproducible and effective SPP based SERS sensor.
