Fig. 4From: Fabrication-friendly polarization-sensitive plasmonic grating for optimal surface-enhanced Raman spectroscopySimulated a maximum and b average values of GSERS as a function of grating fill factor. In a and b, the blue (square) and red (triangle) discrete data points show the GSERS values at the corresponding fill factors calculated over D1 and D2 lines, respectively, while the blue and red vertical axes correspond to the blue and red data pointsBack to article page
