Sentence examples for backward ratio from inspiring English sources
Together, we define the SHG emission directionality (forward to backward ratio) and relative SHG intensity (conversion efficiency based on χ(2)) as the SHG creation attributes.
While SHG lacks the resolution of EM, it provides structural information at both the fibril and fiber levels of organization due to the coherence of the process [ 12], and we will show how the SHG metrics of intensity, and emission directionality, (forward to backward ratio) are consistent with ultra-structural findings.
