WebThe Bloch vector model is based on the torque equation [ 5 ]. In the laboratory frame of reference, for a nucleus with a nonzero magnetic moment, I ≠ 0, the torque Eq. (1) … WebMar 22, 2024 · In this paper, we consider periodic waveguides with a BIC, and study the eigenmodes for given real frequencies near the frequency of the BIC. It turns out that such eigenmodes near the BIC always have a complex Bloch wavenumber, but they may or may not be leaky modes that radiate out power laterally to infinity.
