and slow down the radiation of “left” molecules. More clearly, the
difference in the spontaneous radiation rate of the enantiomers of
chiral molecules is shown in Fig. 4.8.
Note, that from a practical point of view, for the experimental
study of the effect of differences in the rates of spontaneous
radiation of the “right” and “left” molecule enantiomers, the chiral
MNG-metamaterialismorepromising,becausethetechnologyofits
implementation(technologyofthesplitringresonators)isnowwell
established [55, 67]. On the contrary, the chiral DNG-metamaterials
can be also synthesized [46].
