WebHere, we define circular dichroism as the reflection difference between the LCP and RCP incidences, such that CD = R RCP – R LCP. Surprisingly, a change in the twisted angle only leads to the modification of the amplitude of CD signals of the quasi-BIC resonances whereas the resonance wavelengths and Q -factors stay stable (Figure 4d,e ). WebCircular dichroism for four-fold symmetrical structure The circular dichroism CD is defined by CD = T R−T L C D = T R − T L (1) where TR and TL is a transmittance when the right- and the left- circularly polarized plane wave is incident on the device, respectively. flowey nederland
