Fig. 1From: Metal Substrate-Induced Line Width Compression in the Magnetic Dipole Resonance of a Silicon Nanosphere Illuminated by a Focused Azimuthally Polarized Beama The electric field distribution of a focused AP beam at the focal point. b The scattering spectrum of the Si NS suspended in air. The line width of the MD resonance is 53 nm. c The Si NS with R = 100 nm placed on a metal substrate. d The scattering spectrum of the Si NS placed on a PEC substrateBack to article page
