Experimentally, the measured Q-factor of dominant magnetic dipole resonance can achieve no less than a level of ~261 by Lorentzian fitting to the experimental data. In addition, a high Q-factor of the fundamental-order magnetic WebThe presence of quantum Rayleigh scattering, or spontaneous emission, inside a dielectric medium such as a beam splitter or an interferometric filter prevents a single photon from propagating in a straight line. Modelling a beam splitter by means of a unitary transformation is physically meaningless because of the loss of photons. Additional …
