There are several approaches to excite SPR wave, i.e. by using a prism coupler, grating-based structure, waveguide coupling and nanoparticles. Among those methods, diffraction grating offers more simplicity in fabrication and cost-effective. This paper presents the experimental results on the fabrication of grating-based structure and characterization in those fabricated grating. The fabricated structure is also analyzed using Rigorous CoupledWave Analysis (RCWA) method to maximize the SERS electromagnetic field as SERS substrates. SERS substrates are a method to enhance Raman signal.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]grating-based structure,rigorous coupled wave analysis,surface plasmons resonance,Surface-enhanced Raman spectroscopy[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]This research was funded by Sandwich Program, World Class University, Institut Teknologi Bandung and the authors are grateful for facilities supported from Optical Thin-Film Technology Laboratory (OTL) and Photonic Technology Laboratory (PTL) in National Electronics and Computer Technology Center, Thailand.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
