The results show the consistent dominance of the dipole field generated at the rectangular Ag nanotape surfaces of various lengths by a normal incident electromagnetic plane wave of polarization along the long edge. The dipole field is further shown to exhibit monotonous spectral redshifts and increased magnitudes with increased length (ℓ) of the rectangular nanotape. In contrary, the spectral peak and the field magnitude do not show the simple consistent variations with varied apex angle (θ) of the triangular nanotape. The calculated result for the triangular tape does exhibit the largely concentrated near field magnitude at the tip. It is found that a remarkable enhancement factor of 107 is attained at θ = 45° and ℓ = 50 nm.[/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]Computational studies,Electromagnetic plane wave,Enhancement factor,Localized surface plasmon resonance,Near-field enhancement,Simple consistent,Size and shape effect,Spectral redshifts[/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][/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 work was supported by Program Unggulan Perguruan Tinggi DIKTI 2017 from the Indonesian Ministry of Research, Technology, and Higher Education, under Contract No. 3091s/I1.C01.2/KU/2017.[/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]https://doi.org/10.1088/1742-6596/1057/1/012008[/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]
